[news.eclipse.modeling.gmf] Re: A shortcut behaving as a node extension

[Boris Blajer <boris.blajer@xxxxxxxxxxx>]

Hi Fabrice,

When a child is added to N2, the underlying element for the child is 
added to the shared underlying parent element. Furthermore, a notational 
node is added to N2. The corresponding notational node will be added to 
N1 by canonical update if the diagram for the N1 is synchronized. Note 
that even if the diagram is synchronized, you should be able to switch 
it off by adding a canonical style to N1 and forcing it not to be 
canonical using CanonicalStyle_Canonical feature.

Best regards,
Boris
