[jboss-user] [EJB 3.0] - Exception on trying to persist more than one object

I get the following exception on trying to persist more than one bean object: anonymous wrote : | Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.um2.mauction.entity.Enchere.bidder -> com.um2.mauction.entity.Utilisateur | at org.hibernate.engine.CascadingAction$9.noCascade(CascadingAction.java:353) | at org.hibernate.engine.Cascade.cascade(Cascade.java:139) | at org.hibernate.event.def.AbstractFlushingEventListener.cascadeOnFlush(AbstractFlushingEventListener.java:131) | at org.hibernate.event.def.AbstractFlushingEventListener.prepareEntityFlushes(AbstractFlushingEventListener.java:122) | at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:65) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) | at org.hibernate.ejb.AbstractEntityManagerImpl$1.beforeCompletion(AbstractEntityManagerImpl.java:515) | ... 48 more | The objects to be added are related to each other via foreign keys so I'm guessing it's because a dependent object can't find the parent object in the database (which is getting persisted just above in the same function).
