Hey everyone,

for a short happy period i was able to create a gmf diagram from an .emf-File, but not anymore, because of the following exception, when creating my actual .diagram-plugin from my .gmfgen:

Not knowing what I have changed I already reinstalled the epsilon-plugins, but the exception remains and I can' figure out what it wants to tell me.

Any hint is appreciated
thanks in advance

Best regards
David
