• Error using nservicebus with nettiers

  - by Darren

  I'm using the nservicebus springbuilder(below) with compiles and runs fine. However once I add a single DataRepository entry in the code to call nettiers the project compiles but throws an exception on the line below: IBus Bus = Configure.With().SpringBuilder() .XmlSerializer() .MsmqTransport() .IsTransactional(true) .PurgeOnStartup(false) .UnicastBus() .ImpersonateSender(false) .LoadMessageHandlers() .CreateBus() .Start(); Exception: {"Could not load file or assembly 'Microsoft.Practices.Unity, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

• Problem with eager load polymorphic associations using Linq and NHibernate

  - by Voislav

  Is it possible to eagerly load polymorphic association using Linq and NH? For example: Company is base class, Department is inherited from Company, and Company has association Employees to the User (one-to-many) and also association to the Country (many-to-one). Here is mapping part related to inherited class (without User and Country classes): <class name="Company" discriminator-value="Company"> <id name="Id" type="int" unsaved-value="0" access="nosetter.camelcase-underscore"> <generator class="native"></generator> </id> <discriminator column="OrganizationUnit" type="string" length="10" not-null="true"/> <property name="Name" type="string" length="50" not-null="true"/> <many-to-one name="Country" class="Country" column="CountryId" not-null ="false" foreign-key="FK_Company_CountryId" access="field.camelcase-underscore" /> <set name="Departments" inverse="true" lazy="true" access="field.camelcase-underscore"> <key column="DepartmentParentId" not-null="false" foreign-key="FK_Department_DepartmentParentId"></key> <one-to-many class="Department"></one-to-many> </set> <set name="Employees" inverse="true" lazy="true" access="field.camelcase-underscore"> <key column="CompanyId" not-null="false" foreign-key="FK_User_CompanyId"></key> <one-to-many class="User"></one-to-many> </set> <subclass name="Department" extends="Company" discriminator-value="Department"> <many-to-one name="DepartmentParent" class="Company" column="DepartmentParentId" not-null ="false" foreign-key="FK_Department_DepartmentParentId" access="field.camelcase-underscore" /> </subclass> </class> I do not have problem to eagerly load any of the association on the Company: Session.Query<Company>().Where(c => c.Name == "Main Company").Fetch(c => c.Country).Single(); Session.Query<Company>().Where(c => c.Name == "Main Company").FetchMany(c => c.Employees).Single(); Also, I could eagerly load not-polymorphic association on the department: Session.Query<Department>().Where(d => d.Name == "Department 1").Fetch(d => d.DepartmentParent).Single(); But I get NullReferenceException when I try to eagerly load any of the polymorphic association (from the Department): Assert.Throws<NullReferenceException>(() => Session.Query<Department>().Where(d => d.Name == "Department 1").Fetch(d => d.Country).Single()); Assert.Throws<NullReferenceException>(() => Session.Query<Department>().Where(d => d.Name == "Department 1").FetchMany(d => d.Employees).Single()); Am I doing something wrong or this is not supported yet?

• Sending large serialized objects over sockets is failing only when trying to grow the byte Array, bu

  - by FinancialRadDeveloper

  I have code where I am trying to grow the byte array while receiving the data over my socket. This is erroring out. public bool ReceiveObject2(ref Object objRec, ref string sErrMsg) { try { byte[] buffer = new byte[1024]; byte[] byArrAll = new byte[0]; bool bAllBytesRead = false; int iRecLoop = 0; // grow the byte array to match the size of the object, so we can put whatever we // like through the socket as long as the object serialises and is binary formatted while (!bAllBytesRead) { if (m_socClient.Receive(buffer) > 0) { byArrAll = Combine(byArrAll, buffer); iRecLoop++; } else { m_socClient.Close(); bAllBytesRead = true; } } MemoryStream ms = new MemoryStream(buffer); BinaryFormatter bf1 = new BinaryFormatter(); ms.Position = 0; Object obj = bf1.Deserialize(ms); objRec = obj; return true; } catch (System.Runtime.Serialization.SerializationException se) { objRec = null; sErrMsg += "SocketClient.ReceiveObject " + "Source " + se.Source + "Error : " + se.Message; return false; } catch (Exception e) { objRec = null; sErrMsg += "SocketClient.ReceiveObject " + "Source " + e.Source + "Error : " + e.Message; return false; } } private byte[] Combine(byte[] first, byte[] second) { byte[] ret = new byte[first.Length + second.Length]; Buffer.BlockCopy(first, 0, ret, 0, first.Length); Buffer.BlockCopy(second, 0, ret, first.Length, second.Length); return ret; } Error: mscorlibError : The input stream is not a valid binary format. The starting contents (in bytes) are: 68-61-73-43-68-61-6E-67-65-73-3D-22-69-6E-73-65-72 ... Yet when I just cheat and use a MASSIVE buffer size its fine. public bool ReceiveObject(ref Object objRec, ref string sErrMsg) { try { byte[] buffer = new byte[5000000]; m_socClient.Receive(buffer); MemoryStream ms = new MemoryStream(buffer); BinaryFormatter bf1 = new BinaryFormatter(); ms.Position = 0; Object obj = bf1.Deserialize(ms); objRec = obj; return true; } catch (Exception e) { objRec = null; sErrMsg += "SocketClient.ReceiveObject " + "Source " + e.Source + "Error : " + e.Message; return false; } } This is really killing me. I don't know why its not working. I have lifted the Combine from a suggestion on here too, so I am pretty sure this is not doing the wrong thing? I hope someone can point out where I am going wrong

• Storing a set of criteria in another table

  - by bendataclear

  I have a large table with sales data, useful data below: RowID Date Customer Salesperson Product_Type Manufacturer Quantity Value 1 01-06-2004 James Ian Taps Tap Ltd 200 £850 2 02-06-2004 Apple Fran Hats Hats Inc 30 £350 3 04-06-2004 James Lawrence Pencils ABC Ltd 2000 £980 ... Many rows later... ... 185352 03-09-2012 Apple Ian Washers Tap Ltd 600 £80 I need to calculate a large set of targets from table containing values different types, target table is under my control and so far is like: TargetID Year Month Salesperson Target_Type Quantity 1 2012 7 Ian 1 6000 2 2012 8 James 2 2000 3 2012 9 Ian 2 6500 At present I am working out target types using a view of the first table which has a lot of extra columns: SELECT YEAR(Date) , MONTH(Date) , Salesperson , Quantity , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType1 , CASE WHEN Manufacturer = 'Hats Inc' AND Product_Type IN ('Hats','Coats') THEN True ELSE False END AS IsType2 ... ... , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType24 , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType25 FROM SalesTable WHERE [some stuff here] This is horrible to read/debug and I hate it!! I've tried a few different ways of simplifying this but have been unable to get it to work. The closest I have come is to have a third table holding the definition of the types with the values for each field and the type number, this can be joined to the tables to give me the full values but I can't work out a way to cope with multiple values for each field. Finally the question: Is there a standard way this can be done or an easier/neater method other than one column for each type of target? I know this is a complex problem so if anything is unclear please let me know. Edit - What I need to get: At the very end of the process I need to have targets displayed with actual sales: Type Year Month Salesperson TargetQty ActualQty 2 2012 8 James 2000 2809 2 2012 9 Ian 6500 6251 Each row of the sales table could potentially satisfy 8 of the types. Some more points: I have 5 different columns that need to be defined against the targets (or set to NULL to include any value) I have between 30 and 40 different types that need to be defined, several of the columns could contain as many as 10 different values For point 2, if I am using a row for each permutation of values, 2 columns with 10 values each would give me 100 rows for each sales person for each month which is a lot but if this is the only way to define multiple values I will have to do this. Sorry if this makes no sense!

• IDataServiceMetadataProvider - Entities dont show up in $metadata.

  - by TomTom

  I am trying to write our own RIA services provider to expose data from a server that I access via ODBC. I follow th eguidelines set out at http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do. I am putting in a resource set like this: ResourceType tableType = new ResourceType( typeof(Dictionary<string, object>), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; var prodKey = new ResourceProperty( "Key", ResourcePropertyKind.Key | ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(int)) ); prodKey.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodKey); var prodName = new ResourceProperty( "Name", ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(string)) ); prodName.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodName); _MetaDataProvider.AddResourceType(tableType); _MetaDataProvider.AddResourceSet(new ResourceSet(table_name, tableType)); I see the requests coming in for enumerating the resource sets. I check them there in a breakpoint, and the resource set and the type is there, with all properties. Still, the output I get is: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:2377/MartiniData.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> </workspace> </service> And for the $metadata version: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"> - <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0"> - <Schema Namespace="Martini" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm"> <EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" /> </Schema> </edmx:DataServices> </edmx:Edmx> The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?

• Disable keyboard input on Android TimePicker

  - by ashughes

  I'm developing and Android app using the 1.6 sdk. I'm using a TimePicker and I don't want the soft keyboard to come up when you click on the digits in the TimePicker. I only want the TimePicker to be changed using the plus and minus buttons. I've tried using android:focusable="false" and android:focusableInTouchMode="false" hoping those would do it, but they didn't seem to do anything. Is there a way to do this?

I want to get the base64 String of img: WebClient wc = new WebClient(); wc.setThrowExceptionOnFailingStatusCode(false); wc.setThrowExceptionOnScriptError(false); HtmlPage p = wc.getPage("http://flickr.com"); HtmlImage img = (HtmlImage) p.getByXPath("//img").get(3); System.out.println(img.getImageReader().getFormatName());

• ASP.NET MVC3 Custom Membership Provider - The membership provider name specified is invalid.

  - by David Lively

  I'm implementing a custom membership provider, and everything seems to go swimmingly until I create a MembershipUser object. At that point, I receive the error: The membership provider name specified is invalid. Parameter name: providerName In web.config the membership key is <membership defaultProvider="MembersProvider"> <providers> <clear/> <add name="MembersProvider" type="Members.Providers.MembersProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="DeviceDatabase" /> </providers> </membership> When creating the MembershipUser object from my custom User class: public static MembershipUser ToMembershipUser(User user) { MembershipUser member = new MembershipUser ("MembersProvider" , user.Name , user.Id , user.EmailAddress , user.PasswordQuestion , user.Comment , user.IsApproved , user.IsLockedOut , user.DateCreated , user.LastLoginDate ?? DateTime.MinValue , user.LastActivityDate ?? DateTime.MinValue , user.LastPasswordChangedDate ?? DateTime.MinValue , user.LastLockoutDate ?? DateTime.MinValue ); return member; } (I realize I could probably just inherit my User class from MembershipUser, but it's already part of an existing class hierarchy. I honestly think this is the first time I've encountered a legitimate need for for multiple inheritance!) My feeling is that the new MembershipUser(...) providerName parameter is supposed to match what's set in web.config, but, since they match already, I'm at a loss as to how to proceed. Is there a convenient way to get the name of the active membership provider in code? I'm starting to think that using the built-in membership system is overkill and more trouble than it's worth. Edit Not sure if it's relevant, but the custom membership provider class is in a class library, not the main WAP project. Update Here's the contents of the System.Web.Security.Membership.Provider object as show in the VS2010 command window: >eval System.Web.Security.Membership.Provider {Members.Providers.MembersProvider} [Members.Providers.MembersProvider]: {Members.Providers.MembersProvider} base {System.Configuration.Provider.ProviderBase}: {Members.Providers.MembersProvider} ApplicationName: null EnablePasswordReset: true EnablePasswordRetrieval: false MaxInvalidPasswordAttempts: 5 MinRequiredNonAlphanumericCharacters: 0 MinRequiredPasswordLength: 6 PasswordAttemptWindow: 10 PasswordFormat: Function evaluation was aborted.

• Miller-rabin exception number?

  - by nightcracker

  Hey everyone. This question is about the number 169716931325235658326303. According to http://www.alpertron.com.ar/ECM.HTM it is prime. According to my miller-rabin implementation in python with 7 repetitions is is composite. With 50 repetitions it is still composite. With 5000 repetitions it is STILL composite. I thought, this might be a problem of my implementation. So I tried GNU MP bignum library, which has a miller-rabin primality test built-in. I tested with 1000000 repetitions. Still composite. This is my implementation of the miller-rabin primality test: def isprime(n, precision=7): if n == 1 or n % 2 == 0: return False elif n < 1: raise ValueError("Out of bounds, first argument must be > 0") d = n - 1 s = 0 while d % 2 == 0: d //= 2 s += 1 for repeat in range(precision): a = random.randrange(2, n - 2) x = pow(a, d, n) if x == 1 or x == n - 1: continue for r in range(s - 1): x = pow(x, 2, n) if x == 1: return False if x == n - 1: break else: return False return True And the code for the GMP test: #include <gmp.h> #include <stdio.h> int main(int argc, char* argv[]) { mpz_t test; mpz_init_set_str(test, "169716931325235658326303", 10); printf("%d\n", mpz_probab_prime_p(test, 1000000)); mpz_clear(test); return 0; } As far as I know there are no "exceptions" (which return false positives for any amount of repetitions) to the miller-rabin primality test. Have I stumpled upon one? Is my computer broken? Is the Elliptic Curve Method wrong? What is happening here? EDIT I found the issue, which is http://www.alpertron.com.ar/ECM.HTM. I trusted this applet, I'll contact the author his applet's implementation of the ECM is faulty for this number. Thanks. EDIT2 Hah, the shame! In the end it was something that went wrong with copy/pasting on my side. NOR the applet NOR the miller-rabin algorithm NOR my implementation NOR gmp's implementation of it is wrong, the only thing that's wrong is me. I'm sorry.

• Booking form works but does not give feedback

  - by Naim

  I have a form where people can book seats for a given event. It's actually a WordPress plugin. When someone sends his booking, email notifications are sent properly and the event booking status is updated accordingly. The issue is that the booking form does not give any feedback whatsoever. Once you hit "book now", the graphic keeps loading and no feedback is ever displayed like for instance "booking sent successfully" or "there are errors in your form", even though the booking is saved correctly with both sides notified by email. I guess it's a JavaScript issue,Firebug console is not showing any error... So here is the code source of the booking form : Also please experience the issue live Here username: tester password: testsa Thanks! $('#em-booking-form').submit( function(e){ e.preventDefault(); var em_booking_doing_ajax = false; $.ajax({ url: EM.bookingajaxurl, data:$('#em-booking-form').serializeArray(), dataType: 'jsonp', type:'post', beforeSend: function(formData, jqForm, options) { if(em_booking_doing_ajax){ alert(EM.bookingInProgress); return false; } em_booking_doing_ajax = true; $('.em-booking-message').remove(); $('#em-booking').append('<div id="em-loading"></div>'); }, success : function(response, statusText, xhr, $form) { $('#em-loading').remove(); $('.em-booking-message').remove(); $('.em-booking-message').remove(); //show error or success message if(response.result){ $('<div class="em-booking-message-success em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); $('#em-booking-form').hide(); $('.em-booking-login').hide(); $(document).trigger('em_booking_success', [response]); }else{ if( response.errors != null ){ if( $.isArray(response.errors) && response.errors.length > 0 ){ var error_msg; response.errors.each(function(i, el){ error_msg = error_msg + el; }); $('<div class="em-booking-message-error em-booking-message">'+error_msg.errors+'</div>').insertBefore('#em-booking-form'); }else{ $('<div class="em-booking-message-error em-booking-message">'+response.errors+'</div>').insertBefore('#em-booking-form'); } }else{ $('<div class="em-booking-message-error em-booking-message">'+response.message+'</div>').insertBefore('#em-booking-form'); } } $('html, body').animate({ scrollTop: $("#em-booking").first().offset().top - 50 }); //sends user back to top of form //run extra actions after showing the message here if( response.gateway != null ){ $(document).trigger('em_booking_gateway_add_'+response.gateway, [response]); } if( !response.result && typeof Recaptcha != 'undefined'){ Recaptcha.reload(); } }, complete : function(){ em_booking_doing_ajax = false; $('#em-loading').remove(); } }); return false; });

• overload Equals, is this wrong?

  - by Zka

  Reading some piece of code and I keep seeing this : public override bool Equals (object obj) { if (obj == null || this.GetType ().Equals (obj.GetType())) return false; //compare code... } Shouldn't it be like this (note the !): public override bool Equals (object obj) { if (obj == null || !this.GetType ().Equals (obj.GetType())) return false; //compare code... } Or does the equals perform differently in this case?

• Doctrine2 update both sides of association

  - by orourkedd

  I'm using this to update both sides of an association but want to know if there is a more efficient way to do this. In this case, it is a self-referencing OneToMany parent/child association: public function setParent(Node $parent, $inverse = true) { $this->parent = $parent; if($inverse) $parent->addChild($this, false); } public function addChild(Node $child, $inverse = true) { if(!$this->children->contains($child)) { $this->children[] = $child; if($inverse) $child->setParent($this, false); } }

• WPF Open Combobox popup on Focus or GotFocus

  - by ashish.magroria

  Hi, I am trying to open the combobox popup when it is focused using Style/Event Trigger I used the following code in my Combobox control Template: <ControlTemplate x:Key="ComboBoxTemplate" TargetType="{x:Type ComboBox}"> <Grid > <ToggleButton Grid.Column="2" Template="{DynamicResource ComboBoxToggleButton}" x:Name="ToggleButton" Focusable="false" IsChecked="{Binding Path=IsDropDownOpen, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" ClickMode="Press"/> <ContentPresenter HorizontalAlignment="Left" Margin="3,3,23,3" x:Name="ContentSite" VerticalAlignment="Center" Content="{TemplateBinding SelectionBoxItem}" ContentTemplate="{TemplateBinding SelectionBoxItemTemplate}" ContentTemplateSelector="{TemplateBinding ItemTemplateSelector}" IsHitTestVisible="False"/> <TextBox Visibility="Hidden" Template="{DynamicResource ComboBoxTextBox}" HorizontalAlignment="Left" Margin="3,3,23,3" x:Name="PART_EditableTextBox" Style="{x:Null}" VerticalAlignment="Center" Focusable="True" Background="Transparent" IsReadOnly="{TemplateBinding IsReadOnly}"/> <Popup IsOpen="{TemplateBinding IsDropDownOpen}" Placement="Bottom" x:Name="Popup" Focusable="False" AllowsTransparency="True" PopupAnimation="Slide"> <Grid MaxHeight="{TemplateBinding MaxDropDownHeight}" MinWidth="{TemplateBinding ActualWidth}" x:Name="DropDown" SnapsToDevicePixels="True"> <Border x:Name="DropDownBorder" Background="{DynamicResource ShadeBrush}" BorderBrush="{DynamicResource SolidBorderBrush}" BorderThickness="1"/> <ScrollViewer Margin="4,6,4,6" SnapsToDevicePixels="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" CanContentScroll="True"> <StackPanel IsItemsHost="True" KeyboardNavigation.DirectionalNavigation="Contained"/> </ScrollViewer> </Grid> </Popup> </Grid> <ControlTemplate.Triggers> **<Trigger Property="IsMouseOver" Value="True"> <Setter Property="IsOpen" Value="True" TargetName="Popup"/> </Trigger>** </ControlTemplate.Triggers> </ControlTemplate> But nothing happens with this code. So I trid the following Event trigger in ControlTemplate.Triggers <EventTrigger RoutedEvent="UIElement.GotFocus"> <BeginStoryboard> <Storyboard > <BooleanAnimationUsingKeyFrames Storyboard.TargetName="Popup" Storyboard.TargetProperty="IsOpen" FillBehavior="HoldEnd"> <DiscreteBooleanKeyFrame KeyTime="00:00:00" Value="True" /> </BooleanAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="UIElement.LostFocus"> <BeginStoryboard> <Storyboard > <BooleanAnimationUsingKeyFrames Storyboard.TargetName="Popup" Storyboard.TargetProperty="IsOpen" FillBehavior="HoldEnd"> <DiscreteBooleanKeyFrame KeyTime="00:00:00" Value="False" /> </BooleanAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> Now this helps open the popup on focus, but when I select any item from dropdown the pop up doesnt disappear as usual; it stays open. it closes only after I click somewhere else in the window. Can someone please suggest the proper way to do this Thanks in advance

• Displaying a message in a dialog box using AJAX, jQuery, and CakePHP

  - by LainIwakura

  I have a form, and when users submit this form, it should pass the data along to a function using AJAX. Then, the result of that is displayed to the user in a dialog box. I'm using CakePHP (1.3) and jQuery to try and accomplish this but I feel like I'm running into the ground. The form will eventually be used for uploading images with tags, but for now I just want to see a message pop up in the box.. The form: <?php echo $this->Form->create('Image', array('type' => 'file', 'controller' => 'images', 'action' => 'upload', 'method' => 'post')); echo $this->Form->input('Wallpaper', array('type' => 'file')); echo $this->Form->input('Tags'); echo $this->Form->end('Upload!'); ?> The AJAX: $(document).ready(function() { $("#ImageUploadForm").submit(function() { $.ajax({ type: "POST", url: "/images/upload/", data: $(this).serialize(), async: false, success: function(html){ $("#dialog-modal").dialog({ $("#dialog-modal").append("<p>"+html+"</p>"); height: 140, modal: true, buttons: { Ok: function() { $(this).dialog('close'); } } }) } }); return false; }); }); NOTE: if I put $("#dialog-modal").dialog({ height: 140, modal: true }); OUTSIDE of the $.ajax but inside the $("#ImageUploadForm").submit(function() { and comment out the $.ajax stuff, I WILL see a dialog box pop up and then I have to click it for it to go away. After this, it will not forward to the location /images/upload/ The method that AJAX calls: public function upload() { $this->autoRender = false; if ($this->RequestHandler->isAjax()) { echo 'Hi!'; exit(); } } $this-RequestHandler-isAjax() seems to do either absolutely nothing, or it is always returning false. I have never entered an if statement with that as the condition. Thanks for all the help, if you need more information let me know.

• java, swing, Gridlayout problem

  - by josh

  I have a panel with GridLayout But when I'm trying to run the program, only the first button out of 100 is shown. Futhermore, the rest appear only when I move the cursor over them. What's wrong with it? Here's the whole class(Life.CELLS=10 and CellButton is a class which extends JButton) public class MainLayout extends JFrame { public MainLayout() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(650, 750); setLayout(new FlowLayout()); //setResizable(false); final JPanel gridPanel = new JPanel(new GridLayout(Life.CELLS, Life.CELLS)); for (int i=0; i<Life.CELLS; i++) { for (int j=0; j<Life.CELLS; j++) { CellButton jb = new CellButton(i, j); jb.setPreferredSize(new Dimension(jb.getIcon().getIconHeight(), jb.getIcon().getIconWidth())); buttons[i][j] = jb; grid[i][j] = false; gridPanel.add(jb); } } add(gridPanel); } } This is code of CellButton package classes; import javax.swing.JButton; import javax.swing.ImageIcon; import javax.swing.JFrame; public class CellButton extends JButton { private int x; private int y; boolean alive; ImageIcon icon; boolean next; // icons for grids final ImageIcon dead = new ImageIcon(JFrame.class.getResource("/images/image1.gif")); final ImageIcon live = new ImageIcon(JFrame.class.getResource("/images/image2.gif")); public CellButton(int X, int Y) { super(); x = X; y = Y; alive = false; icon = dead; setIcon(icon); } public int getX() { return x; } public int getY() { return y; } public boolean isAlive() { return alive; } public void relive() { alive = true; icon = live; setIcon(icon); } public void die() { alive = false; icon = dead; setIcon(icon); } public void setNext(boolean n) { next = n; } public boolean getNext() { return next; } public ImageIcon getIcon() { return icon; } }

• I'm cloning a table row that contains an input that's being set to jQuery TimeEntry that errors when

  - by Kendall Crouch

  I'm adding a TimeEntry to a page where the user can add a row (clone) to a table. The row that is cloned is hidden (display:none). The user clicks a button and javascript is run to clone the row which renames all of the fields and then appends the new row to the table. <tr id="blankRowShift"> <td> <input type="text" id="timeStart" name="timeStart" /> </td> <td> <input type="text" id="timeEnd" name="timeEnd" /> </td> <td> <select id="userLevel"> <option value="0">Please Select One</option> <option value="2">Admin</option> <option value="1">Employee</option> <option value="3">Scheduler</option> </select> </td> </tr> var r = $("#tbl #blankRowShift").clone().removeAttr("id"); $("#timeStart", r).attr("name", "timeStart" + nn).attr("id", "timeStart" + nn); $("#timeEnd", r).attr("name", "timeEnd" + nn).attr("id", "timeEnd" + nn); $("#userLevel option:nth(0)", r).attr("selected", "selected"); $("#userLevel", r).attr("name", "userLevel" + nn).attr("id", "userLevel" + nn).attr("value", 0); $("#tbl").append(r); $("#timeStart" + nn).timeEntry({ show24Hours: false, showSeconds: false, timeSteps: [1, 15, 0], spinnerImage: 'includes/js/spinnerOrange.png', beforeShow: customRangeStart }); $("#timeStart" + nn).timeEntry('setTime', new Date()); $("#timeEnd" + nn).timeEntry({ show24Hours: false, showSeconds: false, timeSteps: [1, 15, 0], spinnerImage: 'includes/js/spinnerOrange.png', beforeShow: customRangeEnd }); $("#timeEnd" + nn).timeEntry('setTime', new Date()); The spinner works just fine and the times can be changed. Then when submitting the form, I validate the time. The getTime errors in jQuery with the message "elem is undefined var id = elem[ expando ];". I've placed the statement 'console.dir(input)' in the _getTimeTimeEntry: function and it returns nothing for the cloned fields. el = $("#timeStart" + i); if (el.timeEntry("getTime") == null) {
