create an diagram and save in Database i get following Error Messeag

I used some EAnnotation an DataStore-Properties,Unfortunately I was not
successful.
the Error Code:
java.lang.ClassCastException: Identifier classes must be serializable.

org.hibernate.tuple.entity.AbstractEntityTuplizer.getIdentif ier(AbstractEntityTuplizer.java:198)

org.eclipse.emf.teneo.hibernate.tuplizer.EMFTuplizer.getIden tifier(EMFTuplizer.java:94)
