Intersoft Data Extensions for DevForce problem with newest DevForce 2010 v6.1.0

jimmyps — Fri, 20 May 2011 23:15:45 GMT

DevForce 6.0.9 is installed along with the WebUI Studio installation.

To revert back to 6.0.9, please uninstall the newer version, then install 6.0.9 using the DevForce installer located in C:\Program Files (x86)\Intersoft Solutions\Intersoft WebUI Studio 2011 R1\Installer.

Hope this helps.

I too am getting this error of "MissingMethodException" using DevForce.6.1.0 when running the Walkthrough for "Bind UXGridView to DevForce Services using MVVM Pattern".

I just downloaded 6.1.0 from IdeaBlade's web site. While we are waiting for a fix from you guys, how/where do I get 6.0.9?

Hi Jimmy,

I got a MissingMethodException. I have gone back to Devforce 6.09 until this issue is resolved.

Thanks

Chris

Chris,

Which error did you encounter? Is it "FileNotFoundException"? Or is it "MissingMethodException"?

We can replicate the "MissingMethodException" which apparently is a regression in DevForce 6.1.0. IdeaBlade's engineers are still working to resolve this regression bug.

In such case, we assumed that it wasn't the version mismatch (assembly versioning issue) that caused the problem, unless you got a "FileNotFoundException" or "AssemblyVersionMismatchException" error.

Hi Jimmy,

Is there a way to get past this problem until it has been fixed? Can an updated Intersoft.Client.Data.Provider.Devforce.dll be released that works with 6.1?

I am using some newer features in Devforce 6.1 and don't want to go back to 6.09.

Thanks

Chris

Hi Handy,

I don't have time to create a recording. The problem is if you have DevForce 6.1 installed. The intersoft installer installs DevForce 6.09, which does work.

But when you have DevForce 6.1 installed, then the problem is with the line of code:

var query = this.EntityQuery.Parse(queryDescriptor, false)

This is located on line 116 of the DataRepositoryGeneric.cs file located under the ModelServices.Infrastructure folder in the Silverlight project.

The Parse method is an extension method from the assembly Intersoft.Client.Data.Provider.DevForce.dll.

The exception is MissingMethodException which looks like a breaking change in 6.1 which can be found in their release notes for 6.1.

Regards,

Chris

Hello Chris,

I followed the step by step but can run the project well in here. Can you send me a video recording which shows the issue?

Handy

Hi Handy,

I am also having this problem, I have installed DevForce 6.1 with Silverlight 4. This happens when you create a new Silverlight 4 project from the template "Intersoft ClientUI MVVM Data Application (DevForce)" on a machine with DevForce 6.1 installed and run the application and go to the products page.

It looks like Intersoft.Client.Data.Provider.DevForce.dll needs to be fixed up to work with DevForce 6.1

Hi Krzysztof,

Can you let us know if you were using Silverlight or WPF version?
As far I know, this is a known issue in our WPF version. I should work well in Silverlight version.
If you have an issue in Silverlight version, would you mind to help us by sending a simple runable project that replicates the issue?

Regards,
Handy

Hi,

Our data extensions for DevForce EntityQueryExtensions located in assembly "Intersoft.Client.Data.Provider.DevForce.dll" not working correctly
with newest version of DevForce 2010 v6.1.0.

I'm trying use the data provider extension takes the QueryDescriptor as an input. Code is below:

public override void GetTotalItemCount(QueryDescriptor queryDescriptor, Action<int> onSuccess)
{
	var op = this.Manager.Users.Parse(queryDescriptor, false).AsScalarAsync().Count();
	op.Completed += (o, e) =>
	{
		if (onSuccess != null)
			onSuccess(e.Result);
	};
}

This code compiles correctly, but at runtime throws an exception:

System.MissingMethodException was unhandled by user code
  Message=Method not found: 'IdeaBlade.EntityModel.IEntityQuery`1<!!0> IdeaBlade.EntityModel.EntityQueryExtensions.OrderBySelector(IdeaBlade.EntityModel.IEntityQuery`1<!!0>, IdeaBlade.Core.IPropertySortSelector)'.
  StackTrace:
       w Intersoft.Client.Data.Provider.DevForce.EntityQueryExtensions.[TEntity](IEntityQuery`1 query, SortDescriptorCollection sortDescriptors)
       w Intersoft.Client.Data.Provider.DevForce.EntityQueryExtensions.Parse[TEntity](IEntityQuery`1 query, QueryDescriptor queryDescriptor, Boolean applyPageDescriptor)
       w S4MApp.ModelServices.UsersRepository.GetTotalItemCount(QueryDescriptor queryDescriptor, Action`1 onSuccess)
       w S4MApp.ViewModels.UsersViewModel.GetTotalItemCount()
       w S4MApp.ViewModels.UsersViewModel.OnQueryChanged(Object sender, EventArgs e)
       w Intersoft.Client.Data.ComponentModel.QueryDescriptor.?(Object sender, EventArgs e)
       w MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
       w MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

When I downgrade DevForce to version 6.0.8 this code is working properly.
Hope this helps. Thank you.

Krzysztof
