is it normal or bug, that flush() always occurs, even if the transaction rollbacks? i have seam-managed hibernate session configured according to seam documentation http://docs.jboss.com/seam/2.0.0.GA/reference/en/html/persistence.html#d0... <property name="transaction.flush_before_completion">true</property> | <property name="connection.release_mode">after_statement</property> | <property name="transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property> | <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> | and a method @Begin | @End | public void save(Person person){ | currentSession.save(person); | currentSession.createSQLQuery("{call initializePerson(:person_id)}") | .setLong("person_id", person.getId()) | .executeUpdate(); | currentSession.refresh(person); | if (!person.isInitialized()) throw new RuntimeException("Failed to initialize person"); | } | as a result of the method's execution: if person is uninitialized , it will be a rollbacked transaction due to the RuntimeException. (Because it is a "System Exception" and they always cause a transaction rollback http://docs.jboss.com/seam/2.0.0.GA/reference/en/html/events.html#d0e4391 ) As expected the stored procedure "initializePerson" will be rollbacked. But an insert of the method "currentSession.save(person)" will be executed. Because the property transaction.flush_before_completion's value is true. anonymous wrote : if hibernate.transaction.flush_before_completion is enabled, the session will be automatically flushed during the before completion phase of the transaction.(http://www.hibernate.org/hib_docs/reference/en/html/session-... ) | Thus we have 'partial' committed transaction. Imho, it isn't normal behaviour, when an exception occurs. Any suggestions to cause full rollbacking ? (without disabling "flush_before_completion" property or enabling FlushModeType.MANUAL, that seems the same)) Quote: anonymous wrote : Note that Seam does not flush the session, so you should always enable hibernate.transaction.flush_before_completion to ensure that the session is automatically flushed before the JTA transaction commits.http://docs.jboss.com/seam/2.0.0.GA/reference/en/html_single/#d0e...
