petemuir, can you elaborate on this? What does that do,
TransactionType.NOT_SUPPORTED? Does it actually affect flushing?
I'm interested in potentially converting a Struts app backed by Hibernate to
Seam. However we've had to set FlushMode.NEVER in many places because of the
nature of our

One way to stop this is to use TransactionType.NOT_SUPPORTED

I think I've got it all working now with a few tweaks and using

Thanks for the comments.

Yes it is.
Perhaps if you post code and where you are having problems someone can help?
The problem you mention, duplicate entry of child row: perhaps you aren't
creating a new child object for the second add?
I have such a page, it is based on a generic superclass that provides the
standard
This is the parent code:
@Stateful
@Name(eventTypeUpdate)
@Conversational(ifNotBegunOutcome = eventtypefind)
@LoggedIn
public class EventTypeUpdateAction implements EventTypeUpdate {
@PersistenceContext
private EntityManager em;
@In(required = false)
@Out
Sorry mean't action code.
I've not posted the entities as I don't think there is anthing unusual there.

The next problem is that when I delete a child row, the action is persisted to
the db. Is there a way to stop this. I've been digging around for stuff on
@TransactionAttribute(TransactionType.NOT_SUPPORTED)
FlushMode.NEVER got removed from the EJB3 spec unfortunately, I know hibernate
were going to provide it anway but it doesn't seem to be there atm.
