@End commits entity changes!

[whafrog]

How do I end the conversation without letting hibernate commit the entity changes? Editing is a two stage process: edit, then verify. If I call my action's quit method from the edit page (with immediate="true" on the button), all is fine. If I go to the verify page and make the same call to the quit method, the entities are updated anyway.

Button:

<h:commandButton type="submit" value="Quit without Saving" action="#{myaction.quit}" immediate="true"/>

Method:

@End
 @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
 public String quit()
 {
 logger.debug("Quitting without saving");
 return PAGE_MAIN;
 }

If I don't use the @End annotation, nothing is persisted, but then the conversation is out there in memory. Any advice?

Thanks,

Jon

I think this is related to the flush mode of the conversation, look for @Begin(flushMode=FlushModeType.MANUAL),
I think that normally when conversation ends everything is flushed autommatically.

I just posted a somewhat related question but there the conversation is not finished and yet I'm having an update, ok, no more crossposting :P

A call to "entityManager.clear()" seems to solve the problem. Still, you'd think implicit persistence is something you'd have to turn on, not code away.

Thanks, I'll check it out. Probably a better solution than clearing the entitymanager.
