[news.eclipse.modeling.gmf] Update the properties of a link when he is c

[az2004@xxxxxxxxxx (marco )]

hi

I also have a problem with the class the following link:

@gmf.link(source="from",target="to")
abstract class Link extends PropertyHolderElement, TypedElement {
attr LinkNavigability navigability;
ref ConnectableElement[1] from;
ref ConnectableElement[1] to;
ref Component fromContext;
ref Component toContext;
}


I wish that I automatically are assigned the values of the 4 elements 
from, to, fromContext, toContext.

for example if I create a component A with a connectable element B and 
another element component C with a connectable element D.

If I create a link between A and C I want to have in the properties links 
the following values:
from = b
to = c
fromContext = A
toContext = B

I adds a another source and target of the link?
Is there a way to solve this problem?

thank you very much

marco
