org.apache.openjpa.persistence.InvalidStateException: Can only perform

Any new one this ? I would like to cut a milestone soon, so it would
be cool to know if it work out...

Hi Eric,
could you update to current trunk and see if it helps?
We should now only use one session per thread.
Feedback Welcome...

Hi Robert,
maybe I just don't get what you want todo.. How about some "pseudo code" ?
I just committed some code to use only one EntityManager/JCR Session
per request. Hopefully this will help with Alfresco.
Bye,
Norman

Hi Robert,
to be honest I think it would make things just more complicated. I
think we should just make sure we keep the jcr session / entitymanager
etc open till we are done with processing the request. Nothing more...
I don't see the advance of implement such a callback interface. Maybe
you can outline why you "prefer" this way ?
fit in better with the message style API used by the rest of the IMAP
stack. should make transactions transparent and allow scheduling
rather than synchronisation for some operations.
