Enrique, I think that i have to redesign some part of my code, to integrate completely with Spring. I will retest after that refactoring task.
Thank you Sébastien The problem must be that you are using request-scoped beans, don't you? If you use request-scoped beans, then you have to "merge" on every request, using session.merge ;-) There was a discussion about this issue at the beginning of February: http://marc.theaimsgroup.com/?l=myfaces-user&m=113890037426173&w=2 I would recommend using either session-scoped beans, or a session state container, accesible to all your beans, where the current object being worked is available.
