[jboss-user] [EJB 3.0] - EJB3, JSF and Ajax: Exception when cleaning form object attr

Hello People! I am having some trouble with a ajax form. After i have inserted the object on the database through ejb sessionbean and call a method to clean the jsf form by setting null the managed bean object attributes. I receive a message (Transaction Fail) from jsf PhaseListener mecanism, and the operation is undone. My jsf form is something like this: <h:inputText id="address" value="#{managedBean.email.address}" ></h:inputText> Then i have a method that insert in the database through ejb sessionbean and set the email attribuetes to null, include the id. After that i have a method that list the emails. At tgis point it throws an exception on the log, something like this: javax.persistence.PersistenceException: org.hibernate.HibernateException: identifier of an instance of my.entity.Email was altered from 77 to null at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:614) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:76) at my.sessionbean.EmailSessionBean.list(EmailBean.java:54) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) . . . . The interesting thing is that I can perform the operation perfectly with other form with the same template. I think is something related with EJB objects beeing used ad the attribute on the jsf form. So if anyone have any tip, please, let me know. I have searched through out the internet and found no solution. Thanks!!
