Have a look at EcoreUtil.resolve(proxy, context)

but you should actually not get that proxy normally. since it should resolve automatically.
can you please elaborate on what you actually try to do?

in your scope provider you get the context eobject passed as parameter

getScope(context, ereference)

or scope_Bla_Bubb(Bling context, EReference ref)

p.s.: one warning: if you go this way: do not complain about performance. (since you resist to tell you exact usecase we cannot tell you how to put/get the information from the index)
