[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1678) @Begin(flushMode=MANUAL) takes effect AFTER method call instead of before it.

@Begin(flushMode=MANUAL) takes effect AFTER method call instead of before it. ----------------------------------------------------------------------------- Key: JBSEAM-1678 URL: http://jira.jboss.com/jira/browse/JBSEAM-1678 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 2.0.0.BETA1 Environment: J2SE 1.5, Tomcat 6.0.10, Hibernate 3.2.3, HibEM 3.3.1 Reporter: Frits Jalvingh (See also the end of thead at http://jboss.com/index.html?module=bb&op=viewtopic&p=4064502#4064502) I have a method marked: @Begin(flushMode=FlushModeType.MANUAL) public String createNewTarget() This method is meant as the start of a 2-screen conversation. This conversation should be rolled back if a user presses cancel so flushmode=MANUAL is used to prevent the persistence context from flushing db changes. The method starts by creating a new entity and persist()s it. The problem is that this causes an immediate "insert" by Hibernate regardless of the flushmode. I debugged the code and found that the flushmode gets set AFTER Seam calls the method, not before (ConversationInterceptor). This seems to be wrong, so I placed an extra call to set the mode in aroundInvoke(): setFlushMode(method); // JAL FlushMode should be set BEFORE we call the method!? Object result = invocation.proceed(); beginConversationIfNecessary(method, result); endConversationIfNecessary(method, result); return result; (flushMode in the original code is set in beginConversation()). This at least fixes part of the problem; the other part of the problem is a bug in Hibernate where it always forces an insert even if it is not needed. I fixed that too which fixes the entire problem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
