| Creating a node type that is derived from another yields a runtime crash [message #158065] |

I have an .ecore model in which one type ("ArtifactContainer") is
derived from another ("Artifact"). Creating and building the GMF
application went fine. But when I try to create a corresponding object
in a diagram I get a runtime-exception (see error msg. and stack dump
below).
I suspect, that the GMF runtime is somehow confused, which objecttype to
create (I could imagine that more than one Policy might apply or
something of that kind...) and hence fails. What do I need to do or add
to support GMF in handling this case?

Hi Michael,
This issue has been discussed several times here. The most likely cause
is that you have a feature initializer for the derived element, but do
not declare a domain specialization constraint (or declare one that does
not match the initializer).
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=195272 for possible
fixes and/or workarounds.
Best regards,
Boris
