• iTunes 9.0.2 hangs on launch on Mac OS X 10.6.2

  - by dlamblin

  My iTunes 9.0.2 hangs on launch in OS X 10.6.2. This doesn't happen all the time, only if I've been running for a while. Then it will recur until I restart. Similarly Safari 4.0.4 will hang in the flash player plugin when about to play a video. If I restart both these problems go away until later. Based on this crash dump I am suspecting Audio Hijack Pro. I will try to install a newer version of the driver involved, but so far I haven't had much luck. I have uninstalled the Flash Plugin (10.0.r42 and r32) but clearly I want it in the long run. This is iTunes' crash report.

• Android NDK Gaussian Blur radius stuck at 60

  - by rennoDeniro

  I implemented this NDK imeplementation of a Gaussian Blur, But I am having problems. I cannot increase the radius above 60, otherwise the activity just closes returning to a previous activity. No error message, nothing? Does anyone know why this could be?

• WPF animation: binding to the "To" attribute of storyboard animation.

  - by bozalina

  Hi, I'm trying to create a button that behaves similarly to the "slide" button on the iPhone. I have an animation that adjusts the position and width of the button, but I want these values to be based on the text used in the control. Currently, they're hardcoded. Here's my working XAML, so far: <CheckBox x:Class="Smt.Controls.SlideCheckBox" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:Smt.Controls" xmlns:System.Windows="clr-namespace:System.Windows;assembly=PresentationCore" Name="SliderCheckBox" mc:Ignorable="d"> <CheckBox.Resources> <System.Windows:Duration x:Key="AnimationTime">0:0:0.2</System.Windows:Duration> <Storyboard x:Key="OnChecking"> <DoubleAnimation Storyboard.TargetName="CheckButton" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(TranslateTransform.X)" Duration="{StaticResource AnimationTime}" To="40" /> <DoubleAnimation Storyboard.TargetName="CheckButton" Storyboard.TargetProperty="(Button.Width)" Duration="{StaticResource AnimationTime}" To="41" /> </Storyboard> <Storyboard x:Key="OnUnchecking"> <DoubleAnimation Storyboard.TargetName="CheckButton" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(TranslateTransform.X)" Duration="{StaticResource AnimationTime}" To="0" /> <DoubleAnimation Storyboard.TargetName="CheckButton" Storyboard.TargetProperty="(Button.Width)" Duration="{StaticResource AnimationTime}" To="40" /> </Storyboard> <Style x:Key="SlideCheckBoxStyle" TargetType="{x:Type local:SlideCheckBox}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:SlideCheckBox}"> <Canvas> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" RecognizesAccessKey="True" VerticalAlignment="Center" HorizontalAlignment="Center" /> <Canvas> <!--Background--> <Rectangle Width="{Binding ElementName=ButtonText, Path=ActualWidth}" Height="{Binding ElementName=ButtonText, Path=ActualHeight}" Fill="LightBlue" /> </Canvas> <Canvas> <!--Button--> <Button Width="{Binding ElementName=CheckedText, Path=ActualWidth}" Height="{Binding ElementName=ButtonText, Path=ActualHeight}" Name="CheckButton" Command="{x:Static local:SlideCheckBox.SlideCheckBoxClicked}"> <Button.RenderTransform> <TransformGroup> <TranslateTransform /> </TransformGroup> </Button.RenderTransform> </Button> </Canvas> <Canvas> <!--Text--> <StackPanel Name="ButtonText" Orientation="Horizontal" IsHitTestVisible="False"> <Grid Name="CheckedText"> <Label Margin="7 0" Content="{Binding RelativeSource={RelativeSource AncestorType={x:Type local:SlideCheckBox}}, Path=CheckedText}" /> </Grid> <Grid Name="UncheckedText" HorizontalAlignment="Right"> <Label Margin="7 0" Content="{Binding RelativeSource={RelativeSource AncestorType={x:Type local:SlideCheckBox}}, Path=UncheckedText}" /> </Grid> </StackPanel> </Canvas> </Canvas> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource OnChecking}" /> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource OnUnchecking}" /> </Trigger.ExitActions> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </CheckBox.Resources> <CheckBox.CommandBindings> <CommandBinding Command="{x:Static local:SlideCheckBox.SlideCheckBoxClicked}" Executed="OnSlideCheckBoxClicked" /> </CheckBox.CommandBindings> </CheckBox> And the code behind: using System.Windows; using System.Windows.Controls; using System.Windows.Input; namespace Smt.Controls { public partial class SlideCheckBox : CheckBox { public SlideCheckBox() { InitializeComponent(); Loaded += OnLoaded; } public static readonly DependencyProperty CheckedTextProperty = DependencyProperty.Register("CheckedText", typeof(string), typeof(SlideCheckBox), new PropertyMetadata("Checked Text")); public string CheckedText { get { return (string)GetValue(CheckedTextProperty); } set { SetValue(CheckedTextProperty, value); } } public static readonly DependencyProperty UncheckedTextProperty = DependencyProperty.Register("UncheckedText", typeof(string), typeof(SlideCheckBox), new PropertyMetadata("Unchecked Text")); public string UncheckedText { get { return (string)GetValue(UncheckedTextProperty); } set { SetValue(UncheckedTextProperty, value); } } public static readonly RoutedCommand SlideCheckBoxClicked = new RoutedCommand(); void OnLoaded(object sender, RoutedEventArgs e) { Style style = TryFindResource("SlideCheckBoxStyle") as Style; if (!ReferenceEquals(style, null)) { Style = style; } } void OnSlideCheckBoxClicked(object sender, ExecutedRoutedEventArgs e) { IsChecked = !IsChecked; } } } The problem comes when I try to bind the "To" attribute in the DoubleAnimations to the actual width of the text, the same as I'm doing in the ControlTemplate. If I bind the values to an ActualWidth of an element in the ControlTemplate, the control comes up as a blank checkbox (my base class). However, I'm binding to the same ActualWidths in the ControlTemplate itself without any problems. Just seems to be the CheckBox.Resources that have a problem with it. For instance, the following will break it: <DoubleAnimation Storyboard.TargetName="CheckButton" Storyboard.TargetProperty="(Button.Width)" Duration="{StaticResource AnimationTime}" To="{Binding ElementName=CheckedText, Path=ActualWidth}" /> I don't know whether this is because it's trying to bind to a value that doesn't exist until a render pass is done, or if it's something else. Anyone have any experience with this sort of animation binding?

• ASP.Net MVC2 CustomModelBinder not working... Changed from MVC1

  - by Ian

  (My apologies if this seems verbose - trying to provide all relevant code) I've just upgraded to VS2010, and am now having trouble trying to get a new CustomModelBinder working. In MVC1 I would have written something like public class AwardModelBinder: DefaultModelBinder { : public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { // do the base binding to bind all simple types Award award = base.BindModel(controllerContext, bindingContext) as Award; // Get complex values from ValueProvider dictionary award.EffectiveFrom = Convert.ToDateTime(bindingContext.ValueProvider["Model.EffectiveFrom"].AttemptedValue.ToString()); string sEffectiveTo = bindingContext.ValueProvider["Model.EffectiveTo"].AttemptedValue.ToString(); if (sEffectiveTo.Length > 0) award.EffectiveTo = Convert.ToDateTime(bindingContext.ValueProvider["Model.EffectiveTo"].AttemptedValue.ToString()); // etc return award; } } Of course I'd register the custom binder in Global.asax.cs: protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // register custom model binders ModelBinders.Binders.Add(typeof(Voucher), new VoucherModelBinder(DaoFactory.UserInstance("EH1303"))); ModelBinders.Binders.Add(typeof(AwardCriterion), new AwardCriterionModelBinder(DaoFactory.UserInstance("EH1303"), new VOPSDaoFactory())); ModelBinders.Binders.Add(typeof(SelectedVoucher), new SelectedVoucherModelBinder(DaoFactory.UserInstance("IT0706B"))); ModelBinders.Binders.Add(typeof(Award), new AwardModelBinder(DaoFactory.UserInstance("IT0706B"))); } Now, in MVC2, I'm finding that my call to base.BindModel returns an object where everything is null, and I simply don't want to have to iterate all the form fields surfaced by the new ValueProvider.GetValue() function. Google finds no matches for this error, so I assume I'm doing something wrong. Here's my actual code: My domain object (infer what you like about the encapsulated child objects - I know I'll need custom binders for those too, but the three "simple" fields (ie. base types) Id, TradingName and BusinessIncorporated are also coming back null): public class Customer { /// <summary> /// Initializes a new instance of the Customer class. /// </summary> public Customer() { Applicant = new Person(); Contact = new Person(); BusinessContact = new ContactDetails(); BankAccount = new BankAccount(); } /// <summary> /// Gets or sets the unique customer identifier. /// </summary> public int Id { get; set; } /// <summary> /// Gets or sets the applicant details. /// </summary> public Person Applicant { get; set; } /// <summary> /// Gets or sets the customer's secondary contact. /// </summary> public Person Contact { get; set; } /// <summary> /// Gets or sets the trading name of the business. /// </summary> [Required(ErrorMessage = "Please enter your Business or Trading Name")] [StringLength(50, ErrorMessage = "A maximum of 50 characters is permitted")] public string TradingName { get; set; } /// <summary> /// Gets or sets the date the customer's business began trading. /// </summary> [Required(ErrorMessage = "You must supply the date your business started trading")] [DateRange("01/01/1900", "01/01/2020", ErrorMessage = "This date must be between {0} and {1}")] public DateTime BusinessIncorporated { get; set; } /// <summary> /// Gets or sets the contact details for the customer's business. /// </summary> public ContactDetails BusinessContact { get; set; } /// <summary> /// Gets or sets the customer's bank account details. /// </summary> public BankAccount BankAccount { get; set; } } My controller method: /// <summary> /// Saves a Customer object from the submitted application form. /// </summary> /// <param name="customer">A populate instance of the Customer class.</param> /// <returns>A partial view indicating success or failure.</returns> /// <httpmethod>POST</httpmethod> /// <url>/Customer/RegisterCustomerAccount</url> [HttpPost] [ValidateAntiForgeryToken] public ActionResult RegisterCustomerAccount(Customer customer) { if (ModelState.IsValid) { // save the Customer // return indication of success, or otherwise return PartialView(); } else { ViewData.Model = customer; // load necessary reference data into ViewData ViewData["PersonTitles"] = new SelectList(ReferenceDataCache.Get("PersonTitle"), "Id", "Name"); return PartialView("CustomerAccountRegistration", customer); } } My custom binder: public class CustomerModelBinder : DefaultModelBinder { public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { ValueProviderResult vpResult = bindingContext .ValueProvider.GetValue(bindingContext.ModelName); // vpResult is null // MVC2 - ValueProvider is now an IValueProvider, not dictionary based anymore if (bindingContext.ValueProvider.GetValue("Model.Applicant.Title") != null) { // works } Customer customer = base.BindModel(controllerContext, bindingContext) as Customer; // customer instanitated with null (etc) throughout return customer; } } My binder registration: /// <summary> /// Application_Start is called once when the web application is first accessed. /// </summary> protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // register custom model binders ModelBinders.Binders.Add(typeof(Customer), new CustomerModelBinder()); ReferenceDataCache.Populate(); } ... and a snippet from my view (could this be a prefix problem?) <div class="inputContainer"> <label class="above" for="Model_Applicant_Title" accesskey="t"><span class="accesskey">T</span>itle<span class="mandatoryfield">*</span></label> <%= Html.DropDownList("Model.Applicant.Title", ViewData["PersonTitles"] as SelectList, "Select ...", new { @class = "validate[required]" })%> <% Html.ValidationMessageFor(model => model.Applicant.Title); %> </div> <div class="inputContainer"> <label class="above" for="Model_Applicant_Forename" accesskey="f"><span class="accesskey">F</span>orename / First name<span class="mandatoryfield">*</span></label> <%= Html.TextBox("Model.Applicant.Forename", Html.Encode(Model.Applicant.Forename), new { @class = "validate[required,custom[onlyLetter],length[2,20]]", title="Enter your forename", maxlength = 20, size = 20, autocomplete = "off", onkeypress = "return maskInput(event,re_mask_alpha);" })%> </div> <div class="inputContainer"> <label class="above" for="Model_Applicant_MiddleInitials" accesskey="i">Middle <span class="accesskey">I</span>nitial(s)</label> <%= Html.TextBox("Model.Applicant.MiddleInitials", Html.Encode(Model.Applicant.MiddleInitials), new { @class = "validate[optional,custom[onlyLetter],length[0,8]]", title = "Please enter your middle initial(s)", maxlength = 8, size = 8, autocomplete = "off", onkeypress = "return maskInput(event,re_mask_alpha);" })%> </div>

• Optimizing transition/movement smoothness for a 2D flash game.

  - by Tom

  Update 6: Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.html 40 FPS: http://www.feedpostal.com/test/simple/40/SimpleMovement.html 60 FPS: http://www.feedpostal.com/test/simple/60/SimpleMovement.html 100 FPS: http://www.feedpostal.com/test/simple/100/SimpleMovement.html The code: package { import flash.display.Sprite; import flash.events.Event; import flash.events.KeyboardEvent; import flash.utils.getTimer; [SWF(width="800", height="600", frameRate="40", backgroundColor="#000000")] public class SimpleMovement extends Sprite { private static const TURNING_SPEED:uint = 180; private static const MOVEMENT_SPEED:uint = 400; private static const RADIAN_DIVIDE:Number = Math.PI/180; private var playerObject:Sprite; private var shipContainer:Sprite; private var moving:Boolean = false; private var turningMode:uint = 0; private var movementTimestamp:Number = getTimer(); private var turningTimestamp:Number = movementTimestamp; public function SimpleMovement() { //step 1: create player object playerObject = new Sprite(); playerObject.graphics.lineStyle(1, 0x000000); playerObject.graphics.beginFill(0x6D7B8D); playerObject.graphics.drawRect(0, 0, 25, 50); //make it rotate around the center playerObject.x = 0 - playerObject.width / 2; playerObject.y = 0 - playerObject.height / 2; shipContainer = new Sprite(); shipContainer.addChild(playerObject); shipContainer.x = 100; shipContainer.y = 100; shipContainer.rotation = 180; addChild(shipContainer); //step 2: install keyboard hook when stage is ready addEventListener(Event.ADDED_TO_STAGE, stageReady, false, 0, true); //step 3: install rendering update poll addEventListener(Event.ENTER_FRAME, updatePoller, false, 0, true); } private function updatePoller(event:Event):void { var newTime:Number = getTimer(); //turning if (turningMode != 0) { var turningDeltaTime:Number = newTime - turningTimestamp; turningTimestamp = newTime; var rotation:Number = TURNING_SPEED * turningDeltaTime / 1000; if (turningMode == 1) shipContainer.rotation -= rotation; else shipContainer.rotation += rotation; } //movement if (moving) { var movementDeltaTime:Number = newTime - movementTimestamp; movementTimestamp = newTime; var distance:Number = MOVEMENT_SPEED * movementDeltaTime / 1000; var rAngle:Number = shipContainer.rotation * RADIAN_DIVIDE; //convert degrees to radian shipContainer.x += distance * Math.sin(rAngle); shipContainer.y -= distance * Math.cos(rAngle); } } private function stageReady(event:Event):void { //install keyboard hook stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown, false, 0, true); stage.addEventListener(KeyboardEvent.KEY_UP, keyUp, false, 0, true); } private final function keyDown(event:KeyboardEvent):void { if ((event.keyCode == 87) && (!moving)) //87 = W { movementTimestamp = getTimer(); moving = true; } if ((event.keyCode == 65) && (turningMode != 1)) //65 = A { turningTimestamp = getTimer(); turningMode = 1; } else if ((event.keyCode == 68) && (turningMode != 2)) //68 = D { turningTimestamp = getTimer(); turningMode = 2; } } private final function keyUp(event:KeyboardEvent):void { if ((event.keyCode == 87) && (moving)) moving = false; //87 = W if (((event.keyCode == 65) || (event.keyCode == 68)) && (turningMode != 0)) turningMode = 0; //65 = A, 68 = D } } } The results were as I expected. Absolutely no improvement. I really hope that someone has another suggestion as this thing needs fixing. Also, I doubt it's my system as I have a pretty good one (8GB RAM, Q9550 QuadCore intel, ATI Radeon 4870 512MB). Also, everyone else I asked so far had the same issue with my client. Update 5: another example of a smooth flash game just to demonstrate that my movement definitely is different! See http://www.spel.nl/game/bumpercraft.html Update 4: I traced the time before rendering (EVENT.RENDER) and right after rendering (EVENT.ENTER_FRAME), the results: rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 24 ms rendering took: 18 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 232 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms The range is 12-16 ms. During these differences, the shocking/warping/flickering movement was already going on. There is also 1 peak of 232ms, at this time there was a relatively big warp. This is however not the biggest problme, the biggest problem are the continuous small warps during normal movement. Does this give anyone a clue? Update 3: After testing, I know that the following factors are not causing my problem: Bitmap's quality - changed with photoshop to an uglier 8 colours optimized graphic, no improvement at all. Constant rotation of image while turning - disabled it, no improvement at all Browser rendering - tried to use the flash player standalone, no improvement at all I am 100% convinced that the problem lies in either my code or in my algorithm. Please, help me out. It has been almost two weeks (1 week that I asked this question on SO) now and I still have to get my golden answer. Update 1: see bottom for full flex project source and a live demo demonstrating my problem. I'm working on a 2d flash game. Player ships are created as an object: ships[id] = new GameShip(); When movement and rotation information is available, this is being directed to the corresponding ship: ships[id].setMovementMode(1); //move forward Now, within this GameShip object movement works using the "Event.ENTER_FRAME" event: addEventListener(Event.ENTER_FRAME, movementHandler); The following function is then being run: private final function movementHandler(event:Event):void { var newTimeStamp:uint = UtilLib.getTimeStamp(); //set current timeStamp var distance:Number = (newTimeStamp - movementTimeStamp) / 1000 * movementSpeed; //speed = x pixels forward every 1 second movementTimeStamp = newTimeStamp; //update old timeStamp var diagonalChange:Array = getDiagonalChange(movementAngle, distance); //the diagonal position update based on angle and distance charX += diagonalChange[0]; charY += diagonalChange[1]; if (shipContainer) { //when the container is ready to be worked with shipContainer.x = charX; shipContainer.y = charY; } } private final function getDiagonalChange(angle:Number, distance:Number):Array { var rAngle:Number = angle * Math.PI/180; //convert degrees to radian return [Math.sin(rAngle) * distance, (Math.cos(rAngle) * distance) * -1]; } When the object is no longer moving, the event listener will be removed. The same method is being used for rotation. Everything works almost perfect. I've set the project's target FPS to 100 and created a FPS counter. According to the FPS counter, the average FPS in firefox is around 100, while the top is 1000 and the bottom is 22. I think that the bottom and top FPSs are only happening during the initialization of the client (startup). The problem is that the ship appears to be almost perfectly smooth, while it should be just that without the "almost" part. It's almost as if the ship is "flickering" very very fast, you can't actually see it but it's hard to focus on the object while it's moving with your eyes. Also, every now and then, there seems to be a bit of a framerate spike, as if the client is skipping a couple of frames, you then see it quickly warp. It is very difficult to explain what the real problem is, but in general it's that the movement is not perfectly smooth. So, do you have any suggestions on how to make the movement or transition of objects perfectly smooth? Update 1: I re-created the client to demonstrate my problem. Please check it out. The client: http://feedpostal.com/test/MovementTest.html The Actionscript Project (full source): http://feedpostal.com/test/MovementTest.rar An example of a smooth flash game (not created by me): http://www.gamesforwork.com/games/swf/Mission%20Racing_august_10th_2009.swf It took me a pretty long time to recreate this client side version, I hope this will help with solving the problem. Please note: yes, it is actually pretty smooth. But it is definitely not smooth enough.

• Setting a Visual State from a data bound enum in WPF

  - by firoso

  Hey all, I've got a scenario where I want to switch the visiblity of 4 different content controls. The visual states I have set opacity, and collapsed based on each given state (See code.) What I'd like to do is have the visual state bound to a property of my View Model of type Enum. I tried using DataStateBehavior, but it requires true/false, which doesn't work for me. So I tried DataStateSwitchBehavior, which seems to be totally broken for WPF4 from what I could tell. Is there a better way to be doing this? I'm really open to different approaches if need be, but I'd really like to keep this enum in the equation. Edit: The code shouldn't be too important, I just need to know if there's a well known solution to this problem. <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

• WPF: ContentPresenter changing Foreground unexpectedly depending on where styles are located

  - by VLTII

  Hi, I'm having an issue with the ContentPresenter behaving unexpectedly based on whether the styles are located in the Window.Resources or in a ResourceDictionary.

• jQuery hover menu not disappearing

  - by Nathan Loding

  I have a basic menu using some nested UL's, which is pretty standard I think. When hovering over an LI from the "root" menu, I want the UL within that LI to display. Move the mouse off or to another LI, it shows that submenu. Move down to the submenu and it stays while you hover over each element. I had it working with a simple jQuery.hover() set, but then I ran into issues. When on a page, the "root" menu item is given a class of 'current-page' and if that class exists, I want it to display that submenu statically after a mouseout. Hope I explained that well enough. I just tossed a variable into the hover functions so on the mouseout it ran a .show() on the current-page's submenu. Easy. Except that when I move the mouse between the individual LI's of the submenu, it changes back to the current-page submenu. So I attempted to add a timer element based on another question here. That made things worse -- now the submenus just don't disappear. Here's my CSS, markup, and JS ... how the heck do I make this work properly? Markup: <div id="menu"> <div id="navbar"> <ul id="firstmenu"> <li> <a href="http://localhost/site/pageone">page one</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagetwo">barely there</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li class="current-page"> <a href="http://localhost/site/pagetwo">kith & kin</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagethree">focal point</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagefour">products</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagefive">clients</a> </li> </ul> </div></div> And here's the CSS: #navbar { margin: 0; padding: 0; border: 0; text-align: center; } #firstmenu { margin: 6px auto 0 auto; font-size: 16px; list-style-type: none; letter-spacing: -1px; } #firstmenu li { display: inline; position:relative; overflow: hidden; text-align: center; margin-right: 10px; padding: 5px 15px; } #firstmenu a { text-decoration: none; outline: none; color: black; font-weight: 700; width: 75px; cursor: pointer; } .current-page { color: white; background: url(../images/down_arrow.png) bottom center no-repeat; } .current-page a { color: white; border-bottom: 1px solid black; } #firstmenu .current-page a { color: white; } #firstmenu li.hover { color: white; background: url(../images/down_arrow.png) bottom center no-repeat; } #firstmenu li.hover a { color: white; border-bottom: 1px solid black; } #firstmenu li ul li.hover { color: white; background: none; } #firstmenu li ul li.hover a { color: white; border-bottom: none; text-decoration: underline; } #firstmenu li ul { width: 900px; color: white; font-size: .8em; margin-top: 3px; padding: 5px; position: absolute; display: none; } #firstmenu li ul li { list-style: none; display: inline; width: auto; } #firstmenu li ul li a { color: white; font-weight: normal; border: none; } .sub-current-page { font-weight: bold; text-decoration: underline; } #firstmenu li ul li.sub-current-page a { font-weight: bold; } And lastly, my not-at-all-working JS (this is in a $(document).ready(), of course): // Initialize some variables var hideSubmenuTimer = null; var current_page; $('.current-page ul:first').show(); // Prep the menu $('#firstmenu li').hover(function() { // Clear the timeout if it exists if(hideSubmenuTimer) { clearTimeout(hideSubmenuTimer); } // Check if there's a current-page class set if($('li.current-page').length > 0) { current_page = $('li.current-page'); } else { current_page = false; } // If there's a current-page class, hide it if(current_page) { current_page.children('ul:first').hide(); } // Show the new submenu $(this).addClass('hover').children('ul:first').show(); }, function(){ // Just in case var self = this; // Clear the timeout if it exists if(hideSubmenuTimer) { clearTimeout(hideSubmenuTimer); } // Check if there's a current-page class set if($('li.current-page').length > 0) { current_page = $('li.current-page'); } else { current_page = false; } // Set a timeout on hiding the submenu hideSubmenuTimer = setTimeout(function() { // Hide the old submenu $(self).removeClass('hover').children('ul').hide(); // If there's a current-page class, show it if(current_page) { current_page.children('ul:first').show(); current_page.css('color', 'white'); } }, 500); }); So what am I doing so wrong? As a side note, I'm using the $('.current-page ul:first').show() because if I gave .current-page any "display" setting in the CSS, it positioned it really weirdly on the page.

• RESTful services architecture question

  - by abovesun

  This is question more about service architecture strategy, we are building big web system based on rest services on back end. And we are currently trying to build some standard internal to follow while developing rest services. Some queries returns list of entities, for example lets consider we have image galleries retrieving service: /gell_all_galeries, returning next response: <galleries> <gallery> <id>some_gallery_id</id> <name>my photos</name> <photos> <photo> <id>123</id> <name>my photo</name> <location>http://mysite/photo/show/123</location> ...... <author> <id>some_id</id> <name>some name</name> ....... <author> </photo> <photo> ..... </photo> <photo> ..... </photo> <photo> ..... </photo> <photo> ..... </photo> </photos> </gallery> <gallery> .... </gallery> <gallery> .... </gallery> <gallery> .... </gallery> <gallery> .... </gallery> </galleries> As you see here, response quite big and heavy, and not always we need such deep info level. Usual solution is to use or http://ru.wikipedia.org/wiki/Atom elements for each gallery instead of full gallery data: <galleries> <gallery> <id>some_gallery_id</id> <link href="http://mysite/gallery/some_gallery_id"/> </gallery> <gallery> <id>second_gallery_id</id> <link href="http://mysite/gallery/second_gallery_id"/> </gallery> <gallery> .... </gallery> <gallery> .... </gallery> <gallery> .... </gallery> <gallery> .... </gallery> </galleries> The first question, is next: maybe instead we shouldn't even use and types, and just use generic and for all resources that return list objects: <list> <item><link href="http://mysite/gallery/some_gallery_id"/></item> <item><link href="http://mysite/gallery/other_gallery_id"/></item> <item>....</item> </list> And the second question, after user try to retrieve info about some concrete gallery, he'll use for example http://mysite/gallery/some_gallery_id link, what should he see as results? Should it be: <gallery> <id>some_gallery_id</id> <name>my photos</name> <photos> <photo> <id>123</id> <name>my photo</name> <location>http://mysite/photo/show/123</location> ...... <author> <id>some_id</id> <name>some name</name> ....... <author> </photo> <photo> ..... </photo> <photo> ..... </photo> <photo> ..... </photo> <photo> ..... </photo> </photos> </gallery> or : <gallery> <id>some_gallery_id</id> <name>my photos</name> <photos> <photo><link href="http://mysite/photo/11111"/></photo> <photo><link href="http://mysite/photo/22222"/></photo> <photo><link href="http://mysite/photo/33333"/> </photo> <photo> ..... </photo> </photos> </gallery> or <gallery> <id>some_gallery_id</id> <name>my photos</name> <photos> <photo> <link href="http://mysite/photo/11111"/> <author> <link href="http://mysite/author/11111"/> </author> </photo> <photo> <link href="http://mysite/photo/22222"/> <author> <link href="http://mysite/author/11111"/> </author> </photo> <photo> <link href="http://mysite/photo/33333"/> <author> <link href="http://mysite/author/11111"/> </author> </photo> <photo> ..... </photo> </photos> </gallery> I mean if we use link instead of full object info, how deep we should go there? Should I show an author inside photo and so on. Probably my question ambiguous, but what I'm trying to do is create general strategy in such cases for all team members to follow in future.

• Spring security - Reach users ID without passing it through every controller

  - by nilsi

  I have a design issue that I don't know how to solve. I'm using Spring 3.2.4 and Spring security 3.1.4. I have a Account table in my database that looks like this: create table Account (id identity, username varchar unique, password varchar not null, firstName varchar not null, lastName varchar not null, university varchar not null, primary key (id)); Until recently my username was just only a username but I changed it to be the email address instead since many users want to login with that instead. I have a header that I include on all my pages which got a link to the users profile like this: <a href="/project/users/<%= request.getUserPrincipal().getName()%>" class="navbar-link"><strong><%= request.getUserPrincipal().getName()%></strong></a> The problem is that <%= request.getUserPrincipal().getName()%> returns the email now, I don't want to link the user's with thier emails. Instead I want to use the id every user have to link to the profile. How do I reach the users id's from every page? I have been thinking of two solutions but I'm not sure: Change the principal to contain the id as well, don't know how to do this and having problem finding good information on the topic. Add a model attribute to all my controllers that contain the whole user but this would be really ugly, like this. Account account = entityManager.find(Account.class, email); model.addAttribute("account", account); There are more way's as well and I have no clue which one is to prefer. I hope it's clear enough and thank you for any help on this. ====== Edit according to answer ======= I edited Account to implement UserDetails, it now looks like this (will fix the auto generated stuff later): @Entity @Table(name="Account") public class Account implements UserDetails { @Id private int id; private String username; private String password; private String firstName; private String lastName; @ManyToOne private University university; public Account() { } public Account(String username, String password, String firstName, String lastName, University university) { this.username = username; this.password = password; this.firstName = firstName; this.lastName = lastName; this.university = university; } public String getUsername() { return username; } public String getPassword() { return password; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public void setUsername(String username) { this.username = username; } public void setPassword(String password) { this.password = password; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public University getUniversity() { return university; } public void setUniversity(University university) { this.university = university; } public int getId() { return id; } public void setId(int id) { this.id = id; } @Override public Collection<? extends GrantedAuthority> getAuthorities() { // TODO Auto-generated method stub return null; } @Override public boolean isAccountNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isAccountNonLocked() { // TODO Auto-generated method stub return false; } @Override public boolean isCredentialsNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isEnabled() { // TODO Auto-generated method stub return true; } } I also added <%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %> To my jsp files and trying to reach the id by <sec:authentication property="principal.id" /> This gives me the following org.springframework.beans.NotReadablePropertyException: Invalid property 'principal.id' of bean class [org.springframework.security.authentication.UsernamePasswordAuthenticationToken]: Bean property 'principal.id' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? ====== Edit 2 according to answer ======= I based my application on spring social samples and I never had to change anything until now. This are the files I think are relevant, please tell me if theres something you need to see besides this.

This is starting to be something else compared to my initial question, I should maybe start another question. Sorry for my lack of experience in this. I have to read up.

• Project Euler #15

  - by Aistina

  Hey everyone, Last night I was trying to solve challenge #15 from Project Euler: Starting in the top left corner of a 2×2 grid, there are 6 routes (without backtracking) to the bottom right corner. How many routes are there through a 20×20 grid? I figured this shouldn't be so hard, so I wrote a basic recursive function: const int gridSize = 20; // call with progress(0, 0) static int progress(int x, int y) { int i = 0; if (x < gridSize) i += progress(x + 1, y); if (y < gridSize) i += progress(x, y + 1); if (x == gridSize && y == gridSize) return 1; return i; } I verified that it worked for a smaller grids such as 2×2 or 3×3, and then set it to run for a 20×20 grid. Imagine my surprise when, 5 hours later, the program was still happily crunching the numbers, and only about 80% done (based on examining its current position/route in the grid). Clearly I'm going about this the wrong way. How would you solve this problem? I'm thinking it should be solved using an equation rather than a method like mine, but that's unfortunately not a strong side of mine. Update: I now have a working version. Basically it caches results obtained before when a n×m block still remains to be traversed. Here is the code along with some comments: // the size of our grid static int gridSize = 20; // the amount of paths available for a "NxM" block, e.g. "2x2" => 4 static Dictionary<string, long> pathsByBlock = new Dictionary<string, long>(); // calculate the surface of the block to the finish line static long calcsurface(long x, long y) { return (gridSize - x) * (gridSize - y); } // call using progress (0, 0) static long progress(long x, long y) { // first calculate the surface of the block remaining long surface = calcsurface(x, y); long i = 0; // zero surface means only 1 path remains // (we either go only right, or only down) if (surface == 0) return 1; // create a textual representation of the remaining // block, for use in the dictionary string block = (gridSize - x) + "x" + (gridSize - y); // if a same block has not been processed before if (!pathsByBlock.ContainsKey(block)) { // calculate it in the right direction if (x < gridSize) i += progress(x + 1, y); // and in the down direction if (y < gridSize) i += progress(x, y + 1); // and cache the result! pathsByBlock[block] = i; } // self-explanatory :) return pathsByBlock[block]; } Calling it 20 times, for grids with size 1×1 through 20×20 produces the following output: There are 2 paths in a 1 sized grid 0,0110006 seconds There are 6 paths in a 2 sized grid 0,0030002 seconds There are 20 paths in a 3 sized grid 0 seconds There are 70 paths in a 4 sized grid 0 seconds There are 252 paths in a 5 sized grid 0 seconds There are 924 paths in a 6 sized grid 0 seconds There are 3432 paths in a 7 sized grid 0 seconds There are 12870 paths in a 8 sized grid 0,001 seconds There are 48620 paths in a 9 sized grid 0,0010001 seconds There are 184756 paths in a 10 sized grid 0,001 seconds There are 705432 paths in a 11 sized grid 0 seconds There are 2704156 paths in a 12 sized grid 0 seconds There are 10400600 paths in a 13 sized grid 0,001 seconds There are 40116600 paths in a 14 sized grid 0 seconds There are 155117520 paths in a 15 sized grid 0 seconds There are 601080390 paths in a 16 sized grid 0,0010001 seconds There are 2333606220 paths in a 17 sized grid 0,001 seconds There are 9075135300 paths in a 18 sized grid 0,001 seconds There are 35345263800 paths in a 19 sized grid 0,001 seconds There are 137846528820 paths in a 20 sized grid 0,0010001 seconds 0,0390022 seconds in total I'm accepting danben's answer, because his helped me find this solution the most. But upvotes also to Tim Goodman and Agos :) Bonus update: After reading Eric Lippert's answer, I took another look and rewrote it somewhat. The basic idea is still the same but the caching part has been taken out and put in a separate function, like in Eric's example. The result is some much more elegant looking code. // the size of our grid const int gridSize = 20; // magic. static Func<A1, A2, R> Memoize<A1, A2, R>(this Func<A1, A2, R> f) { // Return a function which is f with caching. var dictionary = new Dictionary<string, R>(); return (A1 a1, A2 a2) => { R r; string key = a1 + "x" + a2; if (!dictionary.TryGetValue(key, out r)) { // not in cache yet r = f(a1, a2); dictionary.Add(key, r); } return r; }; } // calculate the surface of the block to the finish line static long calcsurface(long x, long y) { return (gridSize - x) * (gridSize - y); } // call using progress (0, 0) static Func<long, long, long> progress = ((Func<long, long, long>)((long x, long y) => { // first calculate the surface of the block remaining long surface = calcsurface(x, y); long i = 0; // zero surface means only 1 path remains // (we either go only right, or only down) if (surface == 0) return 1; // calculate it in the right direction if (x < gridSize) i += progress(x + 1, y); // and in the down direction if (y < gridSize) i += progress(x, y + 1); // self-explanatory :) return i; })).Memoize(); By the way, I couldn't think of a better way to use the two arguments as a key for the dictionary. I googled around a bit, and it seems this is a common solution. Oh well.

• Problem in Apache CXF (Simple Frontend): 'Already connected'

  - by seanizer

  I am using apache CXF for the first time. I am trying to establish a connection based on the CXF simple front end (Configuration notes) technology. I can't really see what I've done wrong, but I am getting a weird error (see below). I have also posted this question to [email protected], but I haven't received a response yet. Perhaps someone here can help. The service bean that is wrapped here is a Spring / JPA service that does not know anything about the web, I want to use simple frontend to publish it as a web service without having to annotate it with Jax-ws etc. (This works in theory).

• Need help with workflow in Alfresco

  - by Scott Gartner

  Hello SO community, I haven't had any luck getting help in the Alfresco forums, and I'm hoping for more here. We are building an application based on Alfresco and jBPM and I have defined a workflow, but I have either defined it wrong or am missing something or there are bugs in Alfresco integration with jBPM and I need help figuring out which and fixing it. Here is the problem: I have an advanced workflow and I am trying to launch it from JavaScript. Here is the code I'm using to start the workflow: var nodeId = args.nodeid; var document = search.findNode("workspace://SpacesStore/" + nodeId); var workflowAction = actions.create("start-workflow"); workflowAction.parameters.workflowName = "jbpm$nmwf:MyWorkflow"; workflowAction.parameters["bpm:workflowDescription"] = "Please edit: " + document.name; workflowAction.parameters["bpm:assignees"] = [people.getPerson("admin"), people.getPerson("andyg")]; var futureDate = new Date(); futureDate.setDate(futureDate.getDate() + 7); workflowAction.parameters["bpm:workflowDueDate"] = futureDate; workflowAction.execute(document); This runs fine and e-mail sent from the start node's default transition fires just fine. However, when I go looking for the workflow in my task list it is not there, but it is in my completed task list. The default transition (the only transition) from the start node points at a task node which has four transitions. There are 8 tasks and 22 transitions in the workflow. When I use the workflow console to start the workflow and end the start task, it properly follows the default start node transition to the next task. The new task shows up in "show tasks" but does not show up in "show my tasks" (apparently because the task was marked completed for some reason, though it is not in the "end" node). The task is: task id: jbpm$111 , name: nmwf:submitInEditing , properties: 18 If I do "show transitions" it looks just as I would expect: path: jbpm$62-@ , node: In Editing , active: true task id: jbpm$111 , name: nmwf:submitInEditing, title: submitInEditing title , desc: submitInEditing description , properties: 18 transition id: Submit for Approval , title: Submit for Approval transition id: Request Copyediting Review , title: Request Copyediting Review transition id: Request Legal Review , title: Request Legal Review transition id: Request Review , title: Request Review I don't want to post the entire workflow as it's large, but here are the first two nodes: First the swimlanes: <swimlane name="initiator"></swimlane> <swimlane name="Content Providers"> <assignment actor-id="Content Providers"> <actor>#{bpm_assignees}</actor> </assignment> </swimlane> Now the nodes: <start-state name="start"> <task name="nmwf:submitTask" swimlane="initiator"/> <transition name="" to="In Editing"> <action> <runas>admin</runas> <script> /* Code to send e-mail that a new workflow was started. I get this e-mail. */ </script> </action> </transition> </start-state> <task-node name="In Editing"> <task name="nmwf:submitInEditing" swimlane="Content Providers" /> <!-- I put e-mail sending code in each of these transitions, but none are firing. --> <transition to="In Approval" name="Submit for Approval"></transition> <transition to="In Copyediting" name="Request Copyediting Review"></transition> <transition to="In Legal Review" name="Request Legal Review"></transition> <transition to="In Review" name="Request Review"></transition> </task-node> Here is the model for these two nodes: <type name="nmwf:submitTask"> <parent>bpm:startTask</parent> <mandatory-aspects> <aspect>bpm:assignees</aspect> </mandatory-aspects> </type> <type name="nmwf:submitInEditing"> <parent>bpm:workflowTask</parent> <mandatory-aspects> <aspect>bpm:assignees</aspect> </mandatory-aspects> </type> Here is a pseudo-log of running the workflow in the workflow console: :: deploy alfresco/extension/workflow/processdefinition.xml deployed definition id: jbpm$69 , name: jbpm$nmwf:MyWorkflow , title: nmwf:MyWorkflow , version: 28 :: var bpm:assignees* person admin,andyg set var {http://www.alfresco.org/model/bpm/1.0}assignees = [workspace://SpacesStore/73cf1b28-21aa-40ca-9dde-1cff492d0268, workspace://SpacesStore/03297e91-0b89-4db6-b764-5ada2d167424] :: var bpm:package package 1 set var {http://www.alfresco.org/model/bpm/1.0}package = workspace://SpacesStore/6e2bbbbd-b728-4403-be37-dfce55a83641 :: start bpm:assignees bpm:package started workflow id: jbpm$63 , def: nmwf:MyWorkflow path: jbpm$63-@ , node: start , active: true task id: jbpm$112 , name: nmwf:submitTask, title: submitTask title , desc: submitTask description , properties: 16 transition id: [default] , title: Task Done :: show transitions path: jbpm$63-@ , node: start , active: true task id: jbpm$112 , name: nmwf:submitTask, title: submitTask title , desc: submitTask description , properties: 17 transition id: [default] , title: Task Done :: end task jbpm$112 signal sent - path id: jbpm$63-@ path: jbpm$63-@ , node: In Editing , active: true task id: jbpm$113 , name: nmwf:submitInEditing, title: submitInEditing title , desc: submitInEditing description , properties: 17 transition id: Submit for Approval , title: Submit for Approval transition id: Request Copyediting Review , title: Request Copyediting Review transition id: Request Legal Review , title: Request Legal Review transition id: Request Review , title: Request Review :: show tasks task id: jbpm$113 , name: nmwf:submitInEditing , properties: 18 :: show my tasks admin: [there is no output here] I have been making the assumption that the bpm:assignees that I am setting before starting the workflow initially are getting passed to the first task node "In Editing". Clearly the assignees are on the task object and not on the workflow object. I added the assignees aspect to the start-state task so that it could hold them (after I had a problem; initially they were not there) and possibly they are still sitting there, but the start-state has ended before I even get control back from the web script (not that it would help if it wasn't ended, I need it to be in "In Editing" as the start-state is only used to log that the workflow was started). It has always confused me that the properties that I need to set on each task need to be requested before the task is entered (when you choose a transition you must provide the data for the next task before you can actually move to the next task as you have to validate that you have all of the required data first and then signal the transition). However, the code to start the workflow is asynchronous and therefore does not return either the started workflow or the current task (which in my case would be "In Editing"). So, either way you cannot set variables such as bpm:assignees and bpm:dueDate. I wonder if this is the problem with the user task list. I'm setting the assignees in the property list, but maybe those assignees are going to the start-state task and are not getting passed to the "In Editing" task? Note that this is my first jBPM workflow, so please don't assume I know what I'm doing. If you see something that looks off, it probably is and I just don't know it. Thanks in advance for any advice or help,

• Implementing an async "read all currently available data from stream" operation

  - by Jon

  I recently provided an answer to this question: C# - Realtime console output redirection. As often happens, explaining stuff (here "stuff" was how I tackled a similar problem) leads you to greater understanding and/or, as is the case here, "oops" moments. I realized that my solution, as implemented, has a bug. The bug has little practical importance, but it has an extremely large importance to me as a developer: I can't rest easy knowing that my code has the potential to blow up. Squashing the bug is the purpose of this question. I apologize for the long intro, so let's get dirty. I wanted to build a class that allows me to receive input from a console's standard output Stream. Console output streams are of type FileStream; the implementation can cast to that, if needed. There is also an associated StreamReader already present to leverage. There is only one thing I need to implement in this class to achieve my desired functionality: an async "read all the data available this moment" operation. Reading to the end of the stream is not viable because the stream will not end unless the process closes the console output handle, and it will not do that because it is interactive and expecting input before continuing. I will be using that hypothetical async operation to implement event-based notification, which will be more convenient for my callers. The public interface of the class is this: public class ConsoleAutomator { public event EventHandler<ConsoleOutputReadEventArgs> StandardOutputRead; public void StartSendingEvents(); public void StopSendingEvents(); } StartSendingEvents and StopSendingEvents do what they advertise; for the purposes of this discussion, we can assume that events are always being sent without loss of generality. The class uses these two fields internally: protected readonly StringBuilder inputAccumulator = new StringBuilder(); protected readonly byte[] buffer = new byte[256]; The functionality of the class is implemented in the methods below. To get the ball rolling: public void StartSendingEvents(); { this.stopAutomation = false; this.BeginReadAsync(); } To read data out of the Stream without blocking, and also without requiring a carriage return char, BeginRead is called: protected void BeginReadAsync() { if (!this.stopAutomation) { this.StandardOutput.BaseStream.BeginRead( this.buffer, 0, this.buffer.Length, this.ReadHappened, null); } } The challenging part: BeginRead requires using a buffer. This means that when reading from the stream, it is possible that the bytes available to read ("incoming chunk") are larger than the buffer. Remember that the goal here is to read all of the chunk and call event subscribers exactly once for each chunk. To this end, if the buffer is full after EndRead, we don't send its contents to subscribers immediately but instead append them to a StringBuilder. The contents of the StringBuilder are only sent back whenever there is no more to read from the stream. private void ReadHappened(IAsyncResult asyncResult) { var bytesRead = this.StandardOutput.BaseStream.EndRead(asyncResult); if (bytesRead == 0) { this.OnAutomationStopped(); return; } var input = this.StandardOutput.CurrentEncoding.GetString( this.buffer, 0, bytesRead); this.inputAccumulator.Append(input); if (bytesRead < this.buffer.Length) { this.OnInputRead(); // only send back if we 're sure we got it all } this.BeginReadAsync(); // continue "looping" with BeginRead } After any read which is not enough to fill the buffer (in which case we know that there was no more data to be read during the last read operation), all accumulated data is sent to the subscribers: private void OnInputRead() { var handler = this.StandardOutputRead; if (handler == null) { return; } handler(this, new ConsoleOutputReadEventArgs(this.inputAccumulator.ToString())); this.inputAccumulator.Clear(); } (I know that as long as there are no subscribers the data gets accumulated forever. This is a deliberate decision). The good This scheme works almost perfectly: Async functionality without spawning any threads Very convenient to the calling code (just subscribe to an event) Never more than one event for each time data is available to be read Is almost agnostic to the buffer size The bad That last almost is a very big one. Consider what happens when there is an incoming chunk with length exactly equal to the size of the buffer. The chunk will be read and buffered, but the event will not be triggered. This will be followed up by a BeginRead that expects to find more data belonging to the current chunk in order to send it back all in one piece, but... there will be no more data in the stream. In fact, as long as data is put into the stream in chunks with length exactly equal to the buffer size, the data will be buffered and the event will never be triggered. This scenario may be highly unlikely to occur in practice, especially since we can pick any number for the buffer size, but the problem is there. Solution? Unfortunately, after checking the available methods on FileStream and StreamReader, I can't find anything which lets me peek into the stream while also allowing async methods to be used on it. One "solution" would be to have a thread wait on a ManualResetEvent after the "buffer filled" condition is detected. If the event is not signaled (by the async callback) in a small amount of time, then more data from the stream will not be forthcoming and the data accumulated so far should be sent to subscribers. However, this introduces the need for another thread, requires thread synchronization, and is plain inelegant. Specifying a timeout for BeginRead would also suffice (call back into my code every now and then so I can check if there's data to be sent back; most of the time there will not be anything to do, so I expect the performance hit to be negligible). But it looks like timeouts are not supported in FileStream. Since I imagine that async calls with timeouts are an option in bare Win32, another approach might be to PInvoke the hell out of the problem. But this is also undesirable as it will introduce complexity and simply be a pain to code. Is there an elegant way to get around the problem? Thanks for being patient enough to read all of this. Update: I definitely did not communicate the scenario well in my initial writeup. I have since revised the writeup quite a bit, but to be extra sure: The question is about how to implement an async "read all the data available this moment" operation. My apologies to the people who took the time to read and answer without me making my intent clear enough.

• Squid + Dans Guardian (simple configuration)

  - by The Digital Ninja

  I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

• How to implement Google Maps new version of API v2

  - by bapatla

  Hi every one I came to know that google maps has deprecated its previous version API v1 and introduced a new version of google maps API v2. I tried out one example by following some links in google any how i am pretty sure that i got the api key correctly by providing the exact hash key code and managed to get the correct api key. Now i managed to write some code as well but when i tried to execute the code i am getting the errors please help me to solve this here is my code and i even tried the sample codes provided by google play services an i got the same problem this is the sample that i have done by referring some links in google main activity package com.example.apv; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.MapFragment; import

fragmentManager.findFragmentById(R.id.map); GoogleMap googleMap = mapFragment.getMap(); LatLng sfLatLng = new LatLng(37.7750, -122.4183); googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); googleMap.addMarker(new MarkerOptions() .position(sfLatLng) .title("San Francisco") .snippet("Population: 776733") .icon(BitmapDescriptorFactory.defaultMarker( BitmapDescriptorFactory.HUE_AZURE))); googleMap.getUiSettings().setCompassEnabled(true); googleMap.getUiSettings().setZoomControlsEnabled(true); googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sfLatLng, 10)); } } main.xml <?xml

• Reusing XSL template to be invoked with different relative XPaths

  - by meomaxy

  Here is my contrived example that illustrates what I am attempting to accomplish. I have an input XML file that I wish to flatten for further processing. Input file: <BICYCLES> <BICYCLE> <COLOR>BLUE</COLOR> <WHEELS> <WHEEL> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTORS> <REFLECTOR> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </REFLECTOR> <REFLECTOR> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </REFLECTOR> </REFLECTORS> </WHEEL> <WHEEL> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> </WHEEL> </WHEELS> </BICYCLE> </BICYCLES> The input is a list of <BICYCLE> nodes. Each <BICYCLE> has a <COLOR> and optionally has <WHEELS>. <WHEELS> is a list of <WHEEL> nodes, each of which has a few attributes, and optionally has <REFLECTORS>. <REFLECTORS> is a list of <REFLECTOR> nodes, each of which has a few attributes. The goal is to flatten this XML. This is the XSL I'm using: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" xml:space="preserve"/> <xsl:template match="/"> <BICYCLES> <xsl:apply-templates/> </BICYCLES> </xsl:template> <xsl:template match="BICYCLE"> <xsl:choose> <xsl:when test="WHEELS"> <xsl:apply-templates select="WHEELS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="COLOR"/></COLOR> <WHEEL_TYPE/> <FLAT/> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="WHEELS"> <xsl:apply-templates select="WHEEL"/> </xsl:template> <xsl:template match="WHEEL"> <xsl:choose> <xsl:when test="REFLECTORS"> <xsl:apply-templates select="REFLECTORS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="FLAT"/></FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="REFLECTORS"> <xsl:apply-templates select="REFLECTOR"/> </xsl:template> <xsl:template match="REFLECTOR"> <BICYCLE> <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="../../WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="../../FLAT"/></FLAT> <REFLECTOR_NUM><xsl:value-of select="REFLECTOR_NUM"/></REFLECTOR_NUM> <COLOR><xsl:value-of select="COLOR"/></COLOR> <SHAPE><xsl:value-of select="SHAPE"/></SHAPE> </BICYCLE> </xsl:template> </xsl:stylesheet> The output is: <BICYCLES xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </BICYCLES> What I don't like about this is that I'm outputting the color attribute in several forms: <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <COLOR><xsl:value-of select="COLOR"/></COLOR> <COLOR/> It seems like there ought to be a way to make a named template and invoke it from the various places where it is needed and pass some parameter that represents the path back to the <BICYCLE> node to which it refers. Is there a way to clean this up, say with a named template for bicycle fields, for wheel fields and for reflector fields? In the real world example this is based on, there are many more attributes to a "bicycle" than just color, and I want to make this XSL easy to change to include or exclude fields without having to change the XSL in multiple places.

• Issue with Multiple ModalPopups, ValidationSummary and UpdatePanels

  - by Aaron Hoffman

  I am having an issue when a page contains multiple ModalPopups each containing a ValidationSummary Control. Here is the functionality I need: A user clicks a button and a Modal Popup appears with dynamic content based on the button that was clicked. (This functionality is working. Buttons are wrapped in UpdatePanels and the partial page postback calls .Show() on the ModalPopup) "Save" button in ModalPopup causes client side validation, then causes a full page postback so the entire ModalPopup disappears. (ModalPopup could disappear another way - the ModalPopup just needs to disappear after a successful save operation) If errors occur in the codebehind during Save operation, messages are added to the ValidationSummary (contained within the ModalPopup) and the ModalPopup is displayed again. When the ValidationSummary's are added to the PopupPanel's, the ModalPopups no longer display correctly after a full page postback caused by the "Save" button within the second PopupPanel. (the first panel continues to function correctly) Both PopupPanels are displayed, and neither is "Popped-Up", they are displayed in-line. Any ideas on how to solve this?

• Flex Canvas child Randomly resizes

  - by BS_C3

  Hi! I have an application with a viewstack that contains all the components that need to be displayed. The navigation is defined in the main application. All the components are based on canvas. The main application looks like that: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:components="components.*"> <mx:VBox width="1024" height="100%" horizontalCenter="0" verticalGap="0" backgroundColor="#FFFFFF"> <mx:Image id="header" verticalAlign="top" /> <mx:ViewStack id="body" horizontalCenter="0" verticalCenter="0" width="100%" height="100%"> <components:HomePage id="hp" width="100%"/> <components:CollectionSelection id="cs" width="100%"/> <components:SearchEngine id="se" width="100%"/> <components:SearchResult id="sr" width="100%"/> <components:Tray id="tr" width="100%"/> <components:Order id="or" width="100%"/> </mx:ViewStack> <mx:Image id="footer" verticalAlign="bottom" maintainAspectRatio="false" width="100%"/> </mx:VBox> </mx:Application> I'm getting a strange behaviour from the TRAY component. Here's the code for component Tray (I've only left the display info): <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Image id="bg" horizontalCenter="0" verticalCenter="0" width="100%" height="100%" maintainAspectRatio="false"/> <mx:HBox width="100%"> <mx:Button x="20" y="20" label="BACK"/> <mx:Spacer width="100%"/> <mx:LinkBar itemClick="linkbar_itemClick(event)" styleName="GLBLinkBTN" separatorColor="#FFFFFF" separatorWidth="1" > <mx:dataProvider> <mx:Object label="CLEAR"/> <mx:Object label="LOGOUT"/> </mx:dataProvider> </mx:LinkBar> </mx:HBox> <mx:VBox id="mainBox" horizontalCenter="0" verticalCenter="0" verticalGap="0"> <mx:HBox width="100%" height="50" backgroundColor="#60524D" verticalAlign="bottom" paddingBottom="5"> <mx:Label styleName="TRTitle" paddingLeft="15"/> <mx:Spacer width="100%"/> <mx:Label styleName="TRItems" paddingRight="15"/> </mx:HBox> <mx:HorizontalList id="hlist" dataProvider="{TrayData.instance.itemsCollection}" columnCount="{TrayData.instance.hlistColumns}" rowCount="1" itemRenderer="components.TrayItem" horizontalScrollPolicy="off" rollOverColor="#FFFFFF" selectionColor="#FFFFFF" horizontalCenter="0" verticalCenter="0" borderStyle="none" horizontalScrollPosition="{TrayData.instance.hsPosition}" /> <mx:HBox width="100%" backgroundColor="#E7DDDB" height="40" verticalAlign="middle" paddingLeft="20" paddingRight="20"> <mx:Box width="25" verticalAlign="middle" horizontalAlign="left"> <mx:Button id="leftBtn" /> </mx:Box> <mx:Spacer width="100%"/> <mx:Box width="25" verticalAlign="middle" horizontalAlign="right"> <mx:Button id="rightBtn" /> </mx:Box> </mx:HBox> </mx:VBox> </mx:Canvas> All the components are displaying properly. However, sometimes, randomly, the vbox "mainBox" in the tray component is not displaying as it should: the horizontallist shrinks and instead of fully displaying its items, I get horizontal and vertical scrollbars for each item... I'm currently trying to reproduce this behaviour (to get a print screen) but right know, it's working fine... -_-' As soon as I get it work as it shouldn't, I'll upload an image. Here's the code for the itemRenderer (just in case...): <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" > <mx:HBox width="100%" paddingTop="0" paddingBottom="0" paddingRight="3"> <mx:Spacer width="100%"/> <mx:Box width="14" height="14" verticalAlign="middle" horizontalAlign="center"> <mx:Button width="8" height="8"/> </mx:Box> </mx:HBox> <mx:VBox paddingLeft="20" paddingRight="20" verticalGap="15" paddingBottom="15"> <mx:Canvas id="thumbnail"> <mx:Image id="thumbnailBG" /> <mx:Image id="thumbnailIM" /> </mx:Canvas > <mx:VBox width="100%" verticalGap="7"> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label paddingBottom="5"/> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74"opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> <mx:HBox width="100%" height="13"> <mx:Label width="74" opaqueBackground="#ECE5E2"/> <mx:Label /> </mx:HBox> </mx:VBox> <mx:Button /> </mx:VBox> </mx:VBox> Your help would really be appreciated.

• Generic Aggregation of C++ Objects by Attribute When Attribute Name is Unknown at Runtime

  - by stretch

  I'm currently implementing a system with a number of class's representing objects such as client, business, product etc. Standard business logic. As one might expect each class has a number of standard attributes. I have a long list of essentially identical requirements such as: the ability to retrieve all business' whose industry is manufacturing. the ability to retrieve all clients based in London Class business has attribute sector and client has attribute location. Clearly this a relational problem and in pseudo SQL would look something like: SELECT ALL business in business' WHERE sector == manufacturing Unfortunately plugging into a DB is not an option. What I want to do is have a single generic aggregation function whose signature would take the form: vector<generic> genericAggregation(class, attribute, value); Where class is the class of object I want to aggregate, attribute and value being the class attribute and value of interest. In my example I've put vector as return type, but this wouldn't work. Probably better to declare a vector of relevant class type and pass it as an argument. But this isn't the main problem. How can I accept arguments in string form for class, attribute and value and then map these in a generic object aggregation function? Since it's rude not to post code, below is a dummy program which creates a bunch of objects of imaginatively named classes. Included is a specific aggregation function which returns a vector of B objects whose A object is equal to an id specified at the command line e.g. .. $ ./aggregations 5 which returns all B's whose A objects 'i' attribute is equal to 5. See below: #include <iostream> #include <cstring> #include <sstream> #include <vector> using namespace std; //First imaginativly names dummy class class A { private: int i; double d; string s; public: A(){} A(int i, double d, string s) { this->i = i; this->d = d; this->s = s; } ~A(){} int getInt() {return i;} double getDouble() {return d;} string getString() {return s;} }; //second imaginativly named dummy class class B { private: int i; double d; string s; A *a; public: B(int i, double d, string s, A *a) { this->i = i; this->d = d; this->s = s; this->a = a; } ~B(){} int getInt() {return i;} double getDouble() {return d;} string getString() {return s;} A* getA() {return a;} }; //Containers for dummy class objects vector<A> a_vec (10); vector<B> b_vec;//100 //Util function, not important.. string int2string(int number) { stringstream ss; ss << number; return ss.str(); } //Example function that returns a new vector containing on B objects //whose A object i attribute is equal to 'id' vector<B> getBbyA(int id) { vector<B> result; for(int i = 0; i < b_vec.size(); i++) { if(b_vec.at(i).getA()->getInt() == id) { result.push_back(b_vec.at(i)); } } return result; } int main(int argc, char** argv) { //Create some A's and B's, each B has an A... //Each of the 10 A's are associated with 10 B's. for(int i = 0; i < 10; ++i) { A a(i, (double)i, int2string(i)); a_vec.at(i) = a; for(int j = 0; j < 10; j++) { B b((i * 10) + j, (double)j, int2string(i), &a_vec.at(i)); b_vec.push_back(b); } } //Got some objects so lets do some aggregation //Call example aggregation function to return all B objects //whose A object has i attribute equal to argv[1] vector<B> result = getBbyA(atoi(argv[1])); //If some B's were found print them, else don't... if(result.size() != 0) { for(int i = 0; i < result.size(); i++) { cout << result.at(i).getInt() << " " << result.at(i).getA()->getInt() << endl; } } else { cout << "No B's had A's with attribute i equal to " << argv[1] << endl; } return 0; } Compile with: g++ -o aggregations aggregations.cpp If you wish :) Instead of implementing a separate aggregation function (i.e. getBbyA() in the example) I'd like to have a single generic aggregation function which accounts for all possible class attribute pairs such that all aggregation requirements are met.. and in the event additional attributes are added later, or additional aggregation requirements, these will automatically be accounted for. So there's a few issues here but the main one I'm seeking insight into is how to map a runtime argument to a class attribute. I hope I've provided enough detail to adequately describe what I'm trying to do...
