Hello everyone,
Is there a technique available through the existing EMF API that would allow
me to convert a referenced object back to its proxy state as it existed
prior to resolution? I could obviously re-load the model... but I'm trying
to incrementally restore proxy conditions (as if to "undo" the proxy
resolutions) dynamically
Thanks for any thoughts on this,
-Pete

Given some EObject x that's a resolved proxy held by feature f of object
y, you can use EcoreUtil.create(x.eClass()), cast it to InternalEObject,
call setEProxyURI with EcoreUtil.getURI(x), and then use
EcoreUtil.replace(y, f, x, <that proxy object>).
