[news.eclipse.modeling.gmf] Re: how can I get the reference to the eleme

["Begoña Moros" <bmoros@xxxxx>]

Hi Sylvain,

thank you for your answer but I have not been able to apply the MindMap 
example to my case.

Reading the MindMap tutorial, I guessed that after creating the request and 
getting the command, by this code:

        EditPartViewer viewer = selectedElement.getViewer();
        EditPart elementPart = (EditPart) 
viewer.getEditPartRegistry().get(topicViewAdapter.getAdapter(View.class));

the elementPart variable would be referencing to the EditPart of the new 
element (the one created by executing the command).

I have tryed to adapted this example to my case, but the elementPart is 
null. My code has been included in the handleNotificationEvent-method of the 
ProductRequirementEditPart-class, since a new ProductRequirement is created 
programmatically when a specific event happens. It is as follows:

    ...

    IElementType type = ParamMMElementTypes.ProductRequirement_1001;


    ViewAndElementDescriptor viewDescriptor = new 
ViewAndElementDescriptor(new CreateElementRequestAdapter(new 
CreateElementRequest(type)),

         Node.class,

        ((IHintedType) type).getSemanticHint(),

         this.getDiagramPreferencesHint());


    CreateViewAndElementRequest request = new 
CreateViewAndElementRequest(viewDescriptor);


    Command command = catalog.getCommand(request);


    IAdaptable viewAdapter = (IAdaptable) ((List) 
request.getNewObject()).get(0);


    this.getDiagramEditDomain().getDiagramCommandStack().execute(command);


    EditPartViewer viewer = this.getViewer();

    EditPart elementPart = (EditPart) 
viewer.getEditPartRegistry().get(viewAdapter.getAdapter(View.class));

Do you know what is wrong in this code? Probably there is something that I 
did not understand from the tutorial.

Best regards,
            Begoña
