EMF & hiberate, one-to-many mapping [message #709982]

Hi, I'm getting the following error when using a project mapped via Teneo onto hibernate:

java.lang.IllegalArgumentException: Can not set org.eclipse.emf.common.util.EList field emftest.impl.Entity1Impl.attr to org.hibernate.collection.PersistentList

attr is of type EList<> and is auto-generated by the model code generator in EMF. Hibernate is trying to assign a PersistentList collection to this and cannot.

Is there some kind of custom mapping that needs to be setup for this to work?

Thanks, Lee

Hi Lee,
A later reply because I was on holiday. I think that you are not using a Hibernate session created by the SessionFactory
provided by the Teneo datastore. How are you getting the hibernate session?
