Hi ViK,
Have you already tried the Eager or Lazy subclasses of CDOPackageRegistry?
I think these should solve your problem.
Cheers

Eike,
I use Eager and it doesn't solve my problem :(
and I cannot use Lazy, since I need automatic CDO-Native package
registration.
I see that my ResourceSet's CDOViewSetPackageRegistryImpl delegates to
the session's PackageRegistry, but EagerPackageRegistry doesn't seem to
delegate to EPackage.Registry.INSTANCE. Furthermore, "delegateRegistry"
attribute is null.

CDOViewSetPackageRegistryImpl and CDOPackageRegistryImpl are completely
different and not comparable.
I know once we had the possibility to set a delegate registry.
Unfortunately I can't remember anymore the reason that led to removal of
this support. Usually I'm not a fan of the EMF global package registry
because we can't control it exclusively but maybe now that we have the
external refenrences feature it makes sense again to allow delegation to
the global registry.
Vik, can you please file a Bugzilla so that I can investigate how to
enable this (allow it only before the session is opened or even after that)?
Cheers
