Hello everyone,
Is it possible to remove elements in a non-synchronized diagram
environment? Sylvain had the same problem in
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg12882.html
, but the solution of Jan is to generate the code with synchronized =
true, and than customize the CannonicalEditPolicy. My question is, if
this are the only way to remove elements from all diagrams of a model,
why there exist a synchronized option in the .gmfgen? Is there any
solution to remove a element from all diagrams that reference to the
same model element, without to putting synchronized on, and implement a
non synchronized behavior by my own? Because i think the "delete from
diagram" and "delete from model" options are very nice, if its works.
Thank you in advanced,
Tony

Thanks a lot for your answer.
It works, i have installed a very simple CanonicalEditPolicy like this:
installEditPolicy(EditPolicyRoles.CANONICAL_ROLE, new CanonicalEditPolicy(){
@Override
protected List getSemanticChildrenList() {
return Collections.EMPTY_LIST;
}
});
There are still a small problem: The "delete from diagram" action will
be grayed out, if i install a CanonicalEditPolicy. Do you know how i can
re-enable this action?
regards,
Tony
