I have a problem with Hibernate (Annotations). Here are my Entities:



This one works just fine. The other one that does not is here:



Now, the problem: before I persist ProblemEntity, I call:



After this code, I try to save my ProblemEntity and then flush the session object (the same session that retrieved e1). Even though e1 is not transient and has a valid ID (I checked it), Hibernate tries to insert both problemEntity and e1 (in this order). What am I doing wrong? (both classes are mapped in hibernate.cfg.xml)

Marco,

It looks like you need to pick which side of the association is the owner, and on the annotation for the other side, include the mappedBy attribute on the inverse side. This will let the owning side of the association manage the relationship, and tell the inverse side it is not responsible for maintaining that relationship.
