Do I need a Creation Tool for every model respectively figure?

I only want a creation tool for one figure. Because the other figure are depending on the values of the first figure and should be created with the first Figure.

I try to explain this via code:

protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
			IAdaptable info) throws ExecutionException {
        Element newElement = ModelFactory.eINSTANCE.createElement();
        newElement.setValue(SOMEVALUE);

        Diagram owner = (Diagram) getElementToEdit();
        owner.getElements1().add(newElement);

        // this is what I meant - createing the other element in here or is there something else needed?
        // or can I just use my other creationtools here, but make the invisible in the editor?
        Element2 newElement2 = ModelFactory.eINSTANCE.createElement2();
        newElement2.setAttribute(newElement.getInformation());
        owner.getElements2().add(newElement2);
        doConfigure(newElement, monitor, info);

		((CreateElementRequest) getRequest()).setNewElement(newElement);
		return CommandResult.newOKCommandResult(newElement);
	}

Hello,

Your code should work and if there is the correct mapping for Element2 in map model, then diagram update will (eventually) create node for an Element2.

If you want to have exact control on when and where the node for Element2 is created, you may implement a custom editpolicy that responds to CreateViewAndElementRequest filtered by semantic hint of Element1 type

The new policy will return the command which:
* accesses the just created newElement1 from the request.getNewObject()
* navigates to just created newElement2 (specific to your "main" command)
* calls the ViewService directly to create the node for newElement2, similar to the code in CreateCommand
* sets the positions / size of the new node by using ViewUtil.setStructuralFeatureValue(...) similar to the code in SetBoundsCommand, based on the original request location / size

Make sure that the custom editpolicy is registered for the same container (diagram) and that it is registered AFTER the default CreationEditPolicy which will guarantee that the additional command will be executed after the main one.

Hope this helps,
Regards,
Michael

Thanks for your reply.

So I don't need the Creation Tools for the other Elements?
But I need the Create Command for the Element is that correct?

So when I delete the Creation Tools from my *.gmftool, will the Commands also be deleted, or will they be untouched?

The latter

You may ignore the existing command for Element2, modify command for Element1 as in your sample, and follow steps from my prev reply.

Michael
