Hi,
we store our model instances in multiple XMIResource using UUID's. There
is a base resource A which is referenced by resource B and C. Sometimes,
we replace an object in resource A by some other object. The object
should have the same ID as it is referenced by other objects in resource
B and C. What is the best way to do this?
Thanks,
Luzi

Thanks Ed. And is it ok to call setId with an EObject which is not in
the resource, i.e. can I first get the id of the object to replace, then
set the same id for the new object, and finally replace the object in
the resource?

Luzi,
I think that's okay, but it seems better to replace it and then set the ID.
