  • Using Moq at Blend design time

    - by adrian hara
    This might be a bit out there, but suppose I want to use Moq in a ViewModel to create some design time data, like so: public class SomeViewModel { public SomeViewModel(ISomeDependency dependency) { if (IsInDesignMode) { var mock = new Mock<ISomeDependency>(); dependency = mock.Object; // this throws! } } } The mock could be set up to do some stuff, but you get the idea. My problem is that at design-time in Blend, this code throws an InvalidCastException, with the message along the lines of "Unable to cast object of type 'Castle.Proxies.ISomeDependencyProxy2b3a8f3188284ff0b1129bdf3d50d3fc' to type 'ISomeDependency'." While this doesn't necessarily look to be Moq related but Castle related, I hope the Moq example helps ;) Any idea why that is? Thanks!

  • 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,

  • UpdatePanel, Repeater, DataBinding Problem

    - by Gordon Carpenter-Thompson
    In a user control, I've got a Repeater inside of an UpdatePanel (which id displayed inside of a ModalPopupExtender. The Repeater is databound using an array list of MyDTO objects. There are two buttons for each Item in the list. Upon binding the ImageURL and CommandArgument are set. This code works fine the first time around but the CommandArgument is wrong thereafter. It seems like the display is updated correctly but the DTO isn't and the CommandArgument sent is the one that has just been removed. Can anybody spot any problems with the code?

  • Heap Dump Root Classes

    - by Adnan Memon
    We have production system going into infinite loop of full gc and memory drops form 8 gigs to like 1 MB in just 2 minutes. After taking heap dump it tells me there an is an array of java.lang.Object ([Ljava.lang.Object) with millions of java.lang.String objects having same String taking 99% of heap. But it doesn't tell me which class is referencing to this array so that I can fix it in the code. I took the heap dump using jmap tool on JDK 6 and used JProfiler, NetBeans, SAP Memory Analyzer and IBM Memory Analyzer but none of those tell me what is causing this huge array of objects?? ... like what class is referencing to it or contains it. Do I have to take a different dump with different config in order to get that info? ... Or anything else that can help me find out the culprit class causing this ... it will help a lot.

  • What is the structure of a (Data Access) Service Class

    - by jiewmeng
    I learnt that I should be using service classes to persist entities into the database instead of putting such logic in models/controllers. I currently made my service class something like class Application_DAO_User { protected $user; public function __construct(User $user) { $this->user = $user } public function edit($name, ...) { $this->user->name = $name; ... $this->em->flush(); } } I wonder if this should be the structure of a service class? where a service object represents a entity/model? Or maybe I should pass a User object everytime I want to do a edit like public static function edit($user, $name) { $user->name = $name; $this->em->flush(); } I am using Doctrine 2 & Zend Framework, but it shouldn't matter

  • Python: Inheritance of a class attribute (list)

    - by Sano98
    Hi everyone, inheriting a class attribute from a super class and later changing the value for the subclass works fine: class Unit(object): value = 10 class Archer(Unit): pass print Unit.value print Archer.value Archer.value = 5 print Unit.value print Archer.value leads to the output: 10 10 10 5 which is just fine: Archer inherits the value from Unit, but when I change Archer's value, Unit's value remains untouched. Now, if the inherited value is a list, the shallow copy effect strikes and the value of the superclass is also affected: class Unit(object): listvalue = [10] class Archer(Unit): pass print Unit.listvalue print Archer.listvalue Archer.listvalue[0] = 5 print Unit.listvalue print Archer.listvalue Output: 10 10 5 5 Is there a way to "deep copy" a list when inheriting it from the super class? Many thanks Sano

  • How do you get credentials (NetworkCredential) of currently logged in user ?

    - by Ross
    Hi, I'm writing some code to utilise a 3rd party component, and I need to supply an object which implements ICredentials when I start to use it. If I write the following... var credential = new NetworkCredential("MyUsername", "MyPassword"); ...and pass "credential", it's fine. But I would like to pass the credentials of the current user (it's a Windows service, so runs as a specified user). I have tried both of the following, but neither appear to work (or return anything): NetworkCredential credential = System.Net.CredentialCache.DefaultCredentials; NetworkCredential credential = CredentialCache.DefaultNetworkCredentials; Can anyone suggest how to acquire an approriate object, which represents the credentials of the username that the service is running under ? Thanks, Ross

    Does anybody know how to apply a "where in values" type condition using LINQ-to-Entities? I've tried the following but it doesn't work: var values = new[] { "String1", "String2" }; // some string values var foo = model.entitySet.Where(e = values.Contains(e.Name)); I believe this works in LINQ-to-SQL though? Any thoughts?

  • XBAP childWindow control available similar to Silverlight 3 ChildWindow?

    The Silverlight 3 toolkit has a ChildWindow control for model popup like functionality. This is great.

  • FileInfo..ctor(string fileName) throwing exception: bug in SL 4.0 or .NET 4.0?

    - by Duncan Bayne
    The following test case passes in .NET 4.0: var fiT = new FileInfo("myhappyfilename"); Assert.IsNotNull(fiT); ... but fails in Silverlight 4.0 with the following error: System.ArgumentNullException: Value cannot be null. Parameter name: format at System.String.Format(IFormatProvider provider, String format, Object[] args) at System.Environment.GetResourceString(String key, Object[] values) at System.IO.FileSecurityState.EnsureState() at System.IO.FileInfo.Init(String fileName, Boolean checkHost) at System.IO.FileInfo..ctor(String fileName) Either the failure is a bug in SL 4.0, or the non-failure is a bug in .NET 4.0. Anyone know which it is? (For the record, I'm running SL 4.0 on VS 2010 RC, which may be contributing to the problem).

  • Sparse matrices / arrays in Java

    - by DanM
    I'm working on a project, written in Java, which requires that I build a very large 2-D sparse array. Very sparse, if that makes a difference. Anyway: the most crucial aspect for this application is efficency in terms of time (assume loads of memory, though not nearly so unlimited as to allow me to use a standard 2-D array -- the key range is in the billions in both dimensions). Out of the kajillion cells in the array, there will be several hundred thousand cells which contain an object. I need to be able to modify cell contents VERY quickly. Anyway: Does anyone know a particularly good library for this purpose? It would have to be Berkeley, LGPL or similar license (no GPL, as the product can't be entirely open-sourced). Or if there's just a very simple way to make a homebrew sparse array object, that'd be fine too. I'm considering MTJ, but haven't heard any opinions on its quality. Thanks!! -Dan

  • How to get SpecFlow working with xUnit.net as the test runner

    - by Mike Scott
    I'm trying to use xUnit.net as the test runner for SpecFlow. The SpecFlow 1.2 binaries from the official download area don't contain an xUnit.net provider but the master branch on GitHub has one, so I build SpecFlow.Core.dll from that. I'm using xUnit.net 1.5. However, when I change the unitTestProvider name in the app.config in my spec project, I get a null reference custom tool error and the generated .feature.cs file is the single line: Object reference not set to an instance of an object. Has anyone succeeded in getting SpecFlow to work with xUnit.net? If so, how?

  • UIViewController not loading a UIView

    - by Cosizzle
    Hey, I'm playing around with a script my teacher provided for a table based application. However I can't seem to get my own view to load. Files: SubViewOneController (which is a sub view, also has a nib) TapViewController (Custom UIView I created and want to add to a cell) RootViewController (Main controller which loads in the views) SimpleNavAppDelegate How it works: Within the RootViewController, there's an NSArray that holds NSDictionary objects which is declared in the -(void)awakeFromNib {} method - (void)awakeFromNib { // we'll keep track of our views controllers in this array views = [[NSMutableArray alloc] init]; // when using alloc you are responsible for it, and you will have to release it. // ==================================================================================================== // ==================================================================================================== // LOADING IN CUSTOM VIEW HERE: // allocate a set of views and add to our view array as a dictionary item TapViewController *tapBoardView = [[TapViewController alloc] init]; //push onto array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Tab Gestures", @"title", tapBoardView, @"controller", nil]]; [tapBoardView release]; //release the memory // ==================================================================================================== // ==================================================================================================== SubViewOneController *subViewOneController = [[SubViewOneController alloc] init]; // This will set the 2nd level title subViewOneController.title = @"Swipe Gestures"; //set it's title //push it onto the array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Swipe Gestures", @"title", subViewOneController, @"controller", nil]]; [subViewOneController release]; //release the memory } Later on I set the table view: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // OUTPUT -- see console NSLog(@"indexPath %i", indexPath.row); // OUTPUT: tapController: <TapViewController: 0x3b2b360> NSLog(@"view object: %@", [views objectAtIndex:indexPath.row]); // OUTPUT: view object: controller = <TapViewController: 0x3b0e290>; title = "Tab Gestures"; // ----- Hardcoding the controller and nib file in does work, so it's not a linkage issue ------ // UNCOMMENT TO SEE WORKING -- comment below section. //TapViewController *tapContoller = [[TapViewController alloc] initWithNibName:@"TapBoardView" bundle:nil]; //NSLog(@"tapController: %@", tapContoller); //[self.navigationController pushViewController:tapContoller animated:YES]; // ----- Random Tests ----- //UIViewController *targetViewController = [[views objectAtIndex: 0] objectForKey:@"controller"]; // DOES NOT WORK // LOADS THE SECOND CELL (SubViewOneController) however will not load (TapViewController) UIViewController *targetViewController = [[views objectAtIndex: indexPath.row] objectForKey:@"controller"]; NSLog(@"target: %@", targetViewController); // OUTPUT: target: <TapViewController: 0x3b0e290> [self.navigationController pushViewController:targetViewController animated:YES]; } Reading the comments you should be able to see that hardcoding the view in, works - however trying to load it from the View NSArray does not work. It does however contain the object in memory, seeing that NSLog proves that. Everything is linked up and working within the TapViewController nib file. So ya, im kinda stuck on this one, any help would be great! Thanks guys

  • RadGrid cannot pass sortExpression to ObjectDataSourceControl

    - by Jeff
    I have a Telerik RadGrid that bound to a datasource object. They are configured to support custom paging, sorting. For paging, only the data of a page is retrieved from the database. Before sorting, it works fine. The select method of the datasource is like public List<xxx> Select(string sortExpression, int maximumRows, int startRowIndex) {} Before sorting the sortExpression is empty, which is expected. But after use click sort, in the OnSortCommand event handler of Radgrid, the SortExpression is correct, indicating RadGrid has caputre user's sorting correctly. protected void OnSort(object source, GridSortCommandEventArgs e) { Console.WriteLine(e.SortExpression); // correct } But what is strange is that the RadGrid does not pass parameter to DataSource correctly this time. sortExpression is still empty, maximumRows became int.Max, and startRowIndex is 0. The the sorting in still render correctly, but grid ask datasource to get all data and do the sorting locally. Is this bug of RadGrid or my configuration is wrong?

  • Performance: use a BinaryReader on a MemoryStream to read a byte array, or read directly?

    - by Virtlink
    I would like to know whether using a BinaryReader on a MemoryStream created from a byte array (byte[]) would reduce performance significantly. There is binary data I want to read, and I get that data as an array of bytes. I am currently deciding between two approaches to read the data, and have to implement many reading methods accordingly. After each reading action, I need the position right after the read data, and therefor I am considering using a BinaryReader. The first, non-BinaryReader approach: object Read(byte[] data, ref int offset); The second approach: object Read(BinaryReader reader); Such Read() methods will be called very often, in succession on the same data until all data has been read. So, using a BinaryReader feels more natural, but has it much impact on the performance?
