Hello again,
i try to get teneo to work with gmf.
So i set the appropiate EPackages for the datastore.
final EPackage[] ePackages = new EPackage[] {
MyFirstPackage.eINSTANCE,
MySecondPackage.eINSTANCE,
NotationPackage.eINSTANCE, EcorePackage.eINSTANCE,
XMLTypePackage.eINSTANCE };
OneOfMyClasses is contained in both models in different implementation
(don't ask me why)
So i got these Exception:
Caused by: org.hibernate.DuplicateMappingException: Duplicate
class/entity mapping
OneOfMyClasses
I read that i should use a different naming strategy in this case:
datastore.getExtensionManager().registerExtension(
EntityNameStrategy.class.getName(),
QualifyingEntityNameStrategy.class.getName()
);
But now i get a new Exception:
java.lang.IllegalArgumentException: Illegal eClassStr for this resolver
(no dot separating the epackage nsprefix and name): AnyType_mixed
Maybe one of you has a clue what i should do now?
Greetings
Matthias

Hi Matthias,
Hmm, sounds like a bug, can you enter a bugzilla? In the meantime, you can go back to the previous namingstrategy and
annotate one of the OneOfMyClasses eclasses with an @Entity(name="MyUniquName") annotation.
