I seem to have the same problem. I'm running seam 2.0.0b1 with hibernate 3.2.3, hbem 3.3.1 in JPA mode without EJB (Tomcat native). I have a method as follows: | @Transactional(TransactionPropagationType.REQUIRED) | @Begin(flushMode=FlushModeType.MANUAL) | public String createNewTarget() { | System.out.println("method entered (fm=manual we hope)"); | m_target = new Target(); | m_target.setTargetSourceList(new ArrayList<TargetSourceModule>()); | | m_target.setKey("akey"); | m_target.setName("Name"); | System.out.println("method before persist()"); | m_daoBuilder.save(m_target); | System.out.println("method after persist()"); | return "newtarget"; | } | and when this gets called Hibernate immediately inserts the record: | 01:26:41,964 DEBUG [SeamPhaseListener] before phase: INVOKE_APPLICATION 5 | method entered (fm=manual we hope) | method before persist() | Hibernate: select nextval ('ab_target_sq') | *** fix: shouldDelayetc=false, fm=AUTO, ria=true | Hibernate: insert into ab_target (tgt_autoDiscover, tgt_key, tgt_name, tgt_repository_version, tgtid) values (?, ?, ?, ?, ?) | method after persist() | 01:27:03,786 DEBUG [Manager] Beginning long-running conversation | The ***fix line is displayed around the fix you proposed. As you can see flushmode is manual and requireimmediateresult is true. I have debugged thru Seam and found one very odd thing though- the @Begin annotation seems to set the flushmode etc after the method is invoked, not before! It is done in ConversationInterceptor.aroundInvoke; the pertinent code is: | Object result = invocation.proceed(); | beginConversationIfNecessary(method, result); | endConversationIfNecessary(method, result); | return result; | The call to "beginConversation" sets the flush mode, but after the deed has been done. I don't yet know if this is the cause of the problem but having the annotation "start" after the method call seems weird to me to say the least.
