Hi Pascal,
I had the same problem. I think you can solve as follows.
After register your models, you can try to change the field's type to a
Link type :
Class oClass =db.get().getMetadata().getSchema().getClass(ClassB.class);
oClass.dropProperty("classToBeReferenced");
oClass.createProperty("classToBeReferenced", OType.LINK);
it worked in my case.
Let me know if worked for you.
Best regards,
Robson
