Detached entity passed to persist after timeout, but which one?

christophe.carvalho Feb 1, 2011 10:06 AM

Hi,

In my seam application i encountered the following issue :

In a stateful sesion bean i create a persist method which use an EntityHome bean to persist an entity , if i call this method in the first 15 minutes after displaying the xhtml page everything works correctly, but if i wait more than 15 minutes the method result in a "detached entity passed to persist" error.

I have increased the session and the conversation timeout to 30 minutes.

Can someone explain me how to configure the timeout which make my entities being detached after 15 minutes.

Regards,

Here is my environnement :

- JBoss AS 4.3

- Seam 2.2.0 GA

What EJB version do you use?
Could you provide a detailed error stacktrace and a bit code?

I use EJB 3, her is a sample code :

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("activitesByCollaborateurCrossData")
public class activitesByCollaborateurCrossDataBean implements activitesByCollaborateurCrossData {

      ...
      public void persist() {
           feuilleDeTemps.setChargesAssignables(chargesAssignables);

           // Force le rafraichissement des feuilles de temps du collaborateur
           selectedCollaborateur.getFeuilleDeTempses().add(feuilleDeTemps);

           feuilleDeTempsHome.setInstance(feuilleDeTemps);

           if (feuilleDeTemps.getFeuilleDeTempsId() == 0) {
                 feuilleDeTempsHome.persist();
           } else {
                 feuilleDeTempsHome.update();
      }
}

Nobody has encountered the same problem ?

Other case, wait more than 10 minutes, then try to update an entity with entityHome.update() or entityManager.flush()... the updates are not persist in database and the is no error in the log ...

The session and conversation timeouts have been increased to 30 minutes.
