Assuming I have the following:
1. eObjA and eObjB are EObjects
2. eObjA has a containment reference to eObjB
3. eObjB is a proxy (eIsProxy() returns true)
If I do:
Copier myCopier = new Copier(true, true);
Collection<EObject> myCopiedCollection = myCopier.copyAll(eObjA);
I assumed that the copyAll() method, since instantiated with resolveProxies set, would resolve the proxy URI's and then copy the object pointed to by the proxy URI during the copyAll() operation. It doesn't seem to be working that way. My proxy URI's are still pointing to the original objects. I want the eObjB proxy object pointed to to be copied, and then the new reference URI to point to that new copied object.

Vinny,
If you call the getter on eObjA to fetch eObjB, does that resolve the
proxy or is eObjB.eIsProxy() true?
