MVVM Connection Issue

[Kent]

I am trying to do MVVM with the diagram framework. I modified the MVVM example in the Telerik\xaml-sdk on github.

I am getting a crash when doing the following.  I create connector between a shape inside a
container with shape outside the container. Then I drag the shape outside the container into the container.

Then I immediately get this exception with this error message:
{"Unable to cast object of type 'Telerik.Windows.Controls.RadDiagramConnection' to type 'Telerik.Windows.Controls.Diagrams.Extensions.ViewModels.NodeViewModelBase'."} 


Is this a known bug?  Is there a way to do MVVM with diagram when having connectors and containers?

Hello Kent,

This is indeed a known issue which is already fixed. The fix is available in the latest internal build of our RadControls for WPF. It will also be available with the upcoming Q2 2013 SP release.
