Transaction.rollback problem inside my jpdl
Hi.
I have a problem within my JPDL-Flow (seam 2.1.2).
If the Persistenscontext throws an exception inside my action save(), the Transaktion was marked to rollback. After this. if i try to load a childList of my bean region.childList(), i get a lazyloading Exception (session closed),
Can anybody help me please?
I don't understand why the transaction was rollbacked and how should i solve the problem.
Thanks
alex
The following Infos:
1. JPDL of the flow
2. My Parent Actionbean
3. The Exception (inside of save: try to save the entity with null in not nullable Attribute email)
4. The LazyloadingException
