Vikram,
The thread from "Inhibiting EMF Lazy Loading For Manual Proxy URI
Update" a few notes up is dealing with the same issue. As explained
there, the reference to an object in a resource always uses
eObject.eResource().getURI() as the URI, so while a URI mapping can be
used to redirect where the input stream for the URI is located, it
doesn't affect the form in which references are saved. For that, the
resource's URI is always considered the logical URI and will be used
directly. So to rename a resource you must literally rename the
resource (or load it directly with the new renamed URI *before *using it
to resolve references to the old URI).
