- flushMode= MANUAL, when does commit happen? And othe 2007-07-12 - By enzhao

Hi,
I've read the latest reference section 8.3.3
http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/persistence.html#d0e5563
and annotated my long-running conversation with @(protected)(flushMode=MANUAL), wrote
em.flush(); in the @(protected) method. But I still have some questions. When does the
transaction commit happen?
There are several nested conversation in the root conversation. A mother entity
will be created at the beginning of the root conversation, persisted (in order
to fetch the id) during the conversation. The nested conversations just add
elements to the collections of the mother entity. I watched my shell output,
during any nested conversation, each time when i say
| motherEntity.getChildren.add(sonEntity);
|
hibernate inserted a sonEntity to the database and commits (or not commited? )
How to make the persistence of the son entities happen at the end of the root
conversation?
The hibernate.connection.autocommit is true by default, what's the consequence
of setting it to false? I read the hibernate core reference, but did not get
the answer.
And, I want the transaction of the root conversation to roll back (the
persisted motherEntity should be removed) when the root conversation is time
out. How to achieve this?
Any help would be highly appreciated!!
Regards,
Ellen
