[jboss-user] [JBoss Seam] - Re: Help with StaleObjectStateException needed

[davidfed]

I had almost exactly the same problem while trying to get a password changing UI working.  It would work the first time and lose its optimism the second time.

I finally noticed while comparing against your code that I had:

entityManager.merge(currentUser);

instead of:

currentUser = entityManager.merge(currentUser);

With that change it started working and I started backing out all the other things I had tried to get it back to the simplest version.

I subsequently discovered that I needed:

@In @Out(scope=SESSION)
  | private User currentUser;

to get the changes all the way back into the shared instance living in the session context.  I did not previously know that @Out will not automatically outject back to the context @In injected from.
