In a character selection screen I have made a design view model that has a collection of CharacterTemplate, another design view model I made. The CharacterTemplate has a name and image source. Both these properties works nice and I could bind to them in a ListBox and they show as expected.

I then add a list of traits to my CharacterTemplate design model and add a SelectedCharacter property to my root design view model (also of type CharacterTemplate), and I bind an ItemControllers source to this property.

Now, when I regenerate the data set for the root design view model Noesis Studio crashes.

I tried a simpler scenario, where my CharacterTemplate simply contain a collection of numbers, this does not crash, however the list is never populated, and I try to add a number to the dataset manually I am not able to.
