[jboss-user] [JBoss Seam] - Form submit trigger many updates

Hi everybody, I have a class based on the "Seam APplication Framework" defined as | @Name("machineHome") | class MachineHome extends EntityHome<Machine> | I submit a form whose fields are bound to variables of type | #{machineHome.instance.fieldName} | calling the action (I overrid the method just to play with exceptions) | @Override | @Transactional | public String update() | { | try { | getEntityManager().joinTransaction(); | getEntityManager().flush(); | updatedMessage(); | return "updated"; | } catch (Exception e) { | e.printStackTrace(); | return ""; | } | } | When I submit the form I see the following log message | 00:32:57,454 INFO [STDOUT] Hibernate: update public.machines set version=?, start_date=?, status=?, id_unit=?, machine_code=?, purchase_date=?, last_maintenance_date=?, dismission_date=?, expected_life=?, id_machine_type=?, maintenance_category=? where id_machine=? | I see it as many times as the number of fields I modified before submitting the form. This happens if in faces-config.xml I set | <lifecycle> | <phase-listener> | org.jboss.seam.jsf.SeamPhaseListener | </phase-listener> | </lifecycle> | while it does not happen if I set | <lifecycle> | <phase-listener> | org.jboss.seam.jsf.TransactionalSeamPhaseListener | </phase-listener> | </lifecycle> | In both cases the entity manager get flushed (and the changes saved) even if I do not call flush() explicitely and when I call a method that is not tagged as @Transactional. Can anybody help me to understand why that happens and how to flush the entity manager only when I call flush explicitely? Should I use a @Stateful session bean ? Thanks to anybody for help.
