Create Diagram with initial Content [message #664663]

I want to create an editor, which contains a couple of elements after startup. So i modified the method xxxDiagramEditorUtil.createInitialModel(), but my problem is that the elements are only stored in the domain model but not in the notational model. If i add another element to the diagram, everything works fine.

So i think that i have to create nodes for each element i add in the createInitialModel by using the ViewService.createNode(...) - method. But i am not able to managed this correctly. Can someone plz help me ??

Another point i do not really understand is that if i add a getCreateCommand() - method in a generated EditPolicy which extends the normal BaseItemSemanticPolicy nothing happens. The method is not called. Is there another point where i have to define that it should be possible to add an element ??

I hope my points are understandable, because englisch is not my foreign language.
Thanks for help

Thanks for answering, but this is not what i am looking for.
I used the ideas of this tutorial, but if you open the diagram and close the whole eclipse runtime instance without changing anything in the diagram, then after opening the diagram once again all elements are gone and this is the problem i want to solve now
