How to configure branches in XafariBCDemo Win App

Even though I can run the BCDemo application, when I start the XAS tool either from within the application or by just starting the exe I get the following exception:

System.InvalidOperationException: Exception occurs while assigning the 'DetailView, ID:XafariAuthenticationLogonParameters_DetailView' view to WinWindow:
The 'sourceNode' must have either only default aspect or same set of aspects as this node.
Parametername: sourceNode ---> System.ArgumentException: The 'sourceNode' must have either only default aspect or same set of aspects as this node.

Of course, I already added the german aspect to the model, this is why I can start the BCDemo Win app in the first place. So I wonder what model XAS is accessing here and which aspect is missing?

Hello Mariya,

thank you for the support. I did it as you explained and now the XAS application runs. I was also able to configure the branches and everything works as expected.
