Comment 1 Benjamin Muskalla

This happens for almost all elements (eg. new package, new reference).
Another problem: creating new things in an ecore diagram doesn't add it to the context. If this is the cause, good. If not, please open another bug for that.

Handled resource case, which should be null.
