Hi there.

I have a little problem with EEF.
I'm using eclipse LUNA, EMF 2.10.
I have an EMF model and I can generate the two files .eefgen and .components.

Now I want to generate the eef architecture but I get the following error:

java.lang.ClassCastException: org.eclipse.emf.ecore.impl.EClassImpl cannot be cast to org.eclipse.emf.ecore.EEnum
