> When an entity is persisted which does not have its primary key set (and it is not annotated with GeneratedValue annotation), the @PrePersist callback method is not invoked.
> Instead the exception is thrown:
> Caused by: org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): com.bluemedia.system.User
> at org.hibernate.id.Assigned.generate(Assigned.java:33)
> at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:98)
> at org.hibernate.event.def.DefaultPersistEventListener.entityIsTransient(DefaultPersistEventListener.java:131)
> at org.hibernate.event.def.DefaultPersistEventListener.onPersist(DefaultPersistEventListener.java:87)
> at org.hibernate.event.def.DefaultPersistEventListener.onPersist(DefaultPersistEventListener.java:38)
> at org.hibernate.impl.SessionImpl.firePersist(SessionImpl.java:617)
> at org.hibernate.impl.SessionImpl.persist(SessionImpl.java:591)
> at org.hibernate.impl.SessionImpl.persist(SessionImpl.java:595)
> at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:187)
> ... 64 more
> This is in conflict with ejb 3.0-pfd spec, which states (sec. 3.4.2) :
> "The PrePersist and PreRemove callback methods are invoked for a given entity before the respective EntityManager persist and remove operations for that entity are executed."
> Since the spec states that EntityManager's persist operation is executed after the PrePersist callback methods, setting the value of the primary key in a PrePersist callback method seems a reasonable use case.
