Hi,
i am trying to create a element in the diagram edit part with an action.
I tried to do it just like it was written in the GMF Tips
( http://wiki.eclipse.org/GMF_Tips#Creating_New_Elements_And_C orresponding_Views).
Well, the only difference i have is that i don't want to add a element
to the main DiagramEditPart instead of a compartment. When the action
gets started, you can see that something changes in the diagram, but
only when you create some element with the toolbar manually, the
elements that were created with the action are drawn.
The code of the action is below:
DiagramEditPart parent = selectedElement;
IElementType type = Req_metamodelElementTypes.Document_1001;
ViewAndElementDescriptor viewDescriptor = new
ViewAndElementDescriptor(new CreateElementRequestAdapter(new
CreateElementRequest(type)),
Node.class,
((IHintedType)type).getSemanticHint(),
selectedElement.getDiagramPreferencesHint());
CreateViewAndElementRequest req = new
CreateViewAndElementRequest(viewDescriptor);
CompoundCommand cmd = new CompoundCommand();
cmd.add(parent.getCommand(req));
selectedElement.getDiagramEditDomain()
.getDiagramCommandStack()
.execute(cmd);
I hope someone has time to help me with this little issue.
Thx in advance, Arne :)

Just solved it, doing it like this :) :
CreateViewRequest documentReq =
CreateViewRequestFactory.getCreateShapeRequest(Req_metamodel ElementTypes.Document_1001,
selectedElement.getDiagramPreferencesHint());
org.eclipse.gef.commands.Command createDocument =
selectedElement.getCommand(documentReq);
selectedElement.getDiagramEditDomain()
.getDiagramCommandStack()
.execute(createDocument);
