Hello,
I have downloaded Diagram/MVVM_WPF examples, but when I run example, make a connection e.g. between R8 and Golf blocks, and after this move R8 block into Volkswagen container I got an exception "Unable to cast object of type 'Telerik.Windows.Controls.RadDiagramConnection' to type 'Telerik.Windows.Controls.Diagrams.Extensions.ViewModels.NodeViewModelBase'."
How to resolve this issue?
