Chris, thanks so much for the reply. You're right, this got rid of the hibernate exception. However I'm still missing something. This is the code as it stands right now:
| KidBean kid = parent.getKids().get(mappingIndex); | em.remove(kid); | But when I go to reference the parent again the kid is still there. What's worse is that I noticed in the database a new entry has been created for the kid. (So it's not the same one, but a new one, if you want to be technical - one with almost all the same properties.) This is the DB table before the remove: | sa=> select * from tdm_user_mapping; | mapping_id | user_id | entity_type | entity_id | ------------+---------+-------------+----------- | 450 | 100 | group | 50 | 550 | 100 | group | 100 | and after, notice that one with mapping_id 550 is the one removed: | sa=> select * from tdm_user_mapping; | mapping_id | user_id | entity_type | entity_id | ------------+---------+-------------+----------- | 450 | 100 | group | 50 | 600 | 100 | group | 100 | Trying various combinations of em.refresh(parent), em.merge(parent) and em.find(Parent.class, parentId) result in either nothing happening or a new exception: | Caused by: java.lang.RuntimeException: | org.jboss.tm.JBossRollbackException: Unable to commit, | tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=michael- | litherlands-computer.local/112, BranchQual=, localId=112] | status=STATUS_NO_TRANSACTION; - nested throwable: | (javax.persistence.EntityNotFoundException: | org.hibernate.ObjectDeletedException: deleted entity passed to persist: | [org.me.KidBean#<null>]) | So clearly I'm missing something else. I'm sure it's just that my heads not in the right place. Could I get another hint from anybody?
