In the log, the OptimisticLockException (OLE) shows up somewhere between the following two statements: [SeamPhaseListener] after phase: INVOKE_APPLICATION(5) | #Several other statements here | #The exception stack traces followed immediately by the next line: | [SeamPhaseListener] before phase: RENDER_RESPONSE(6) Also, the OLE is caused by a org.hibernate.StaleObjectStateException. The OLE causes org.jboss.tm.JBossRollbackException which then causes java.lang.IllegalStateException. I try catching all of them in exceptions.xml, but none of them work! <exceptions> | <exception class="org.hibernate.StaleObjectStateException"> | <redirect>optimistic lock exception</redirect> | </exception> | </exceptions> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006608#...
