EPackage with no ResourceSet? [message #1479472]

Hi there,

in some OCL registration code I get a NPE because the code
ePackage.eResource().getResourceSet() returns null. The ePackage is just
a normal EMF model registered via the Extension Point
org.eclipse.emf.ecore.generated_package.

Under what circumstances can the ResourceSet be null for an ePackage?

Cheers,
Hauke

Hauke,

Generated package instances are generally not in any resource set.
