[news.eclipse.modeling.gmf] Re: Adding SpecializationTypes dynamically

[Chris Klapdohr <klapdohr@xxxxxx>]

Hi David,
thanks for your answer.

I have implemented the Interface IHintedType, but I still get the 
"not-allowed" cursor by trying to add one of my SpecializationTypes.

 By debugging I found, that a node that can be added to the canvas 
unlike my SpecializationTypes gets a Comand "cmd" in the method "Command 
getCommand(Request request)" which is not null, so the method 
_disableCanonicalEditPolicyList.addAll(disableCanonicalFor(_request)) is 
called. In case of adding one of my SpecializaitonTypes the Command cmd 
is allways null.

Any ideas whats missing here?

Best regard, Chris
