Hi,

In your model factory implementation class, there should be a method like createPackageNameDiagramModelObject() like method. Here PackageName should be your model package name and DiagramModelObject would be the model object you selected as the diagram element. In this create method you need to create the model object corresponding to the node you want to be created and add it to the diagram model object (into the corresponding containment feature). This will automatically initialize your diagram with a node corresponding to the object you added to the diagram element.

Hope this helps.

Thanks for the answer.
But i could have solved already it.
I post my solution hereIt could be useful for someone else
Just extend the performFinish method in XXXCreationWizard class with the code, which add both view and element to the model.

		IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
		IEditorPart ep = page.getActiveEditor();
		DiagramEditPart diagramEditPart = ((DiagramEditor)ep).getDiagramEditPart();
		
		TopEvent topEvent = FtaFactory.eINSTANCE.createTopEvent(); 
		topEvent.setName("Top Event");
		CreateViewAndElementRequest.ViewAndElementDescriptor veDescriptor = new CreateViewAndElementRequest.ViewAndElementDescriptor(
																						new CreateElementRequestAdapter(new CreateElementRequest(FtaElementTypes.getElementType(TopEventEditPart.VISUAL_ID))), 
																						Node.class, 
																						((IHintedType) FtaElementTypes.getElementType(TopEventEditPart.VISUAL_ID)).getSemanticHint(), 
																						diagramEditPart.getDiagramPreferencesHint()
																				);
		CreateViewAndElementRequest veRequest = new CreateViewAndElementRequest(veDescriptor);
		Command veCommand = diagramEditPart.getCommand(veRequest);
		veCommand.execute();
