I try to make a node invisible in an action with:
Node n = (Node) selectedElement.getNotationView();
n.setVisible(false);
This works, but only after a new object is added or deleted from the
diagram. How can I make this happen "inside" the action?
Even better in this case would be to only delete the view of the node
(not the domain element)
I tried:
stack.execute(new ICommandProxy(new DestroyElementCommand(new
DestroyElementRequest(root, true))));
But this destroys both.
Any ideas?
Best Regards,
Tomas Zijdemans

Solved it with:
selectedElement.getFigure().setVisible(false);

Ok, new problem!
When I reopen the diagram, nodes that have been set to visible(false) is
visible!
How can I prevent this?

I didn't about those :)
How can I ensure that the editparts stay invisible after the diagram is
reopened?
The absolute best solution for me (what I'm really trying to
accomplish), is to replace an edit part.
I have A super of B, through an action the user should be able to
"convert" between them. Now I create new nodes - in the same location -
and set the old one invisible. This is obviously not a good solution...

Hi Tomas,
In this case, I would recommend to have a property in the model to
control the appearance of the node (and persist it). NodeMapping's for
the possible variants should be associated with constraints. AFAIK GMF
will automatically change the visualID (and thus the visual appearance)
in response to modification of the property. If it does not, executing
refresh on the canonical edit policy of the parent should help.
Best regards,
Boris
