"The limitation of this approach is that if a property is mapped on the "

"might relax this in a future release of Hibernate.) The identity generator "
"strategy is not allowed in union subclass inheritance, indeed the primary "
"key seed has to be shared accross all unioned subclasses of a hierarchy."

"La limitation de cette approche est que si une propriété est mappée sur la "
