How one can call the digram creation wizard by a custom Action
(org.eclipse.jface.action.Action)?
Thanks

Hi Alex and Julia.
First, thank you Julia for posting your solution!
Second, is it possible to create the diagram without launching the
wizard? (The action creates a new diagram with default values)
Best Regards,
Tomas Zijdemans

Thanks for helping (again) Alex :)
I've basically just copied the code in (as you can see below). The only
thing that gave an error was:
EditPart targetEditPart = getTargetEditPart(request);
so I replaced it with:
EditPart targetEditPart = selectedElement;
My question is:
What do I put in the run method? - I guess the getOpenCommand have to be
called.. but with what kind of reqest as parameter?
Regards,
Tomas
