All I can say is that it's useful in some corner cases. If I remember correctly, Yoann is right about abstract @Embedded properties. Creating the classes at enhancement time could be a possibility but I'm not sure we have all the information required to do that when we enhance the entities. I think it goes without saying but we still need to have ORM working without enhancement, considering how many bugs we have related to enhanced classes. -- Guillaume _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
