I got it now! ;)
The problem was, that I subTyped ENamedElement in the metamodel.ecore,
which is not allowed, because ENamedElement is not an EClass...
When subTyping EClass instead of ENamedElement the workflow executes without errors.
But I think it's strange that the EcoreEditor as well as the DynamicInstanceEditor no
warnings or errors have been given!?!?
