i tried to create a simple class diagram editor. I defined one figure that should be reused by 4 different meta model elements: Class, Interface, Datatype and Enumeration.
It works well for Class, Interface and Datatype. But when i try to create a Enumeration using the Palette, it fails to create a corresponding view for it.
The exception raised is:
Caused by: org.eclipse.core.runtime.AssertionFailedException: null argument:failed to create a view
I have no idea why this happens, as it works well for the other 3 cases.
I attached my GMF Model files. Maybe i'm just too blind to see the error.
Thanks in advance for your help.
