Hi,
we have an editor, which has already been used by the customer. So we
have some existing data. Now we had to change some elements and changed
some views as well on customer request. One figure has now 2 external
labels mapped to features, which did exist before, but didn't have any
labels. It works well for new diagrams. But, if I open one of the old
diagrams, the external labels will never be displayed, probably because
they do not exist in the legacy diagram data.
I tried everything to display these labels, playing around with
canonical edit policies and stuff, but I'm stuck and running out of
time. Does anybody have an idea, how to create/refresh/enable/display
these (new) external labels?
I think my question is more general: Is there a way to update diagram
views, if the graphical model or mapping model has been changed?
Thanks in advance.

Yeah, this would work, but our editor has only one file for model AND
diagram. So I can't 'delete' the diagram easily, I would have to modify
each file and I wonder, if there isn't a better solution while
initializing the diagram. The other drawback is even worse, because our
diagrams may be quite large (multiple pages printout) and I'm afraid
re-arranging every diagram manually is not acceptable for the customer.

Doesn't anyone else have an idea how to display the new external labels,
when opening the old model diagrams? :-( I expect no complete code
example how to do it, just some hints, which bring me back on the road.
Is it really that complicated?
Any help is appreciated.
Thanks, Holger

Hello Holger,
I think you could find the view element from the notational model using the
EcoreUtil.CrossReferencer class (have a look at org.eclipse.gmf.internal.
codegen.util.EmfUtils) and change the notational view model element
according to your new figure layout.
Regards
Enrico

Hi Alex,
many thanks, this was a big help for me. The resource handler postLoad()
was exactly what I was looking for. I'm now iterating through the
notational model and search for missing (external label) nodes and
create some:
while (it.hasNext()) {
Node node = it.next();
...
// Checking for type "5026" children
...
Node n = node.createChild(NotationPackage.Literals.NODE);
n.setType("5026");
n.setLayoutConstraint(NotationFactory.eINSTANCE.createLocati on());
...
}
I'm not sure, if this is 100% correct, but it does the job.
Regards,
Holger
