|ECrossReferenceAdapter missing links [message #988840]

I noticed somewhat strange during the usage of the ECrossReferenceAdapter, maybe someone can give me a hint on how to solve this problem.
I have 3 Models, Model A, B and AB (adapter is registered for the ResourceSet where the modelElements of AB life, i have atm 3 ResourceSets, one for each model);
A and B are models on their own, and AB is some kind of link-model to link elements from A and B.
So an Element from AB has a reference to one element of A and also to B.
Asking the inverses from an Element in Model B (which happens to be UML) gets me not only the inverses in Model B, but also the link from Model AB.
Asking the same for an Element in Model A only gets me the Elements from Model A, but none from the Model AB.
The notifications are generated so the adapter should somehow notice that something has change.
Could this be that in the ResourceSet-Implementation of UML it is somehow considered this case? But the Adapter is registered for the linkmodel ... so why doesn't he know the inverse from model A?
I tried to get a look into the ResourceSetImpl for the UML-Stuff which was my only hinch.
Maybe someone of you some kind of idea.

I would have expected that resolving a proxy would be handled by this:
protected void handleCrossReference(EReference reference,
EObject notifier = (EObject)notification.getNotifier();
EReference feature = (EReference)notification.getFeature();
if (!feature.isMany() || notification.getPosition() !=
EObject oldValue = (EObject)notification.getOldValue();
if (oldValue != null)
inverseCrossReferencer.remove(notifier, feature, oldValue);
EObject newValue = (EObject)notification.getNewValue();
if (newValue != null)
inverseCrossReferencer.add(notifier, feature, newValue);
