When i try to execute a transformation in ETL from a EMF model to another EMF model, i get following exception:

It happens every time I use an InMemoryEmfModel, but only if the EPackage is registered via an EPackage.Descriptor.

Reproducible: Always

Steps to Reproduce:
1. Create two EMF metamodels and register the packages via extension point org.eclipse.emf.ecore.generated_package.
2. Set up two InMemoryEmfModels and define some rules in ETL.
2. Run the transformation.

Possible fix

This patch fixes the problem for me.
I changed the code so it does not skip the packages registered via EPackage.Descriptor.
Comment 2 Dimitris Kolovos CLA 2012-01-09 03:05:01 EST 
This has been fixed in the SVN and will appear in the next interim version.
