[esb-issues] [JBoss JIRA] (JBESB-3865) AbstractBpm5Action is registering handlers too freely

AbstractBpm5Action is registering handlers too freely ----------------------------------------------------- Key: JBESB-3865 URL: https://issues.jboss.org/browse/JBESB-3865 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Process flow Affects Versions: 4.11 Reporter: Tom Cunningham Assignee: Tom Cunningham Fix For: 4.12 Explanation from Rick Wagner's BZ : AbstractBpm5Action is doing some handler registration for *each* process instance start and service callback: .... ksession.getWorkItemManager().registerWorkItemHandler("JBossESB", esbhandler); ksession.getWorkItemManager().registerWorkItemHandler("ESBAction", actionhandler); ksession.getWorkItemManager().registerWorkItemHandler("Human Task", khandler); 'khandler' in particular is an instance of CommandBasedHornetQWSHumanTaskHandler by default. So when the user goes to close a task, all those handlers fire (JPA trips up, too): 012-08-22 12:32:06,006 INFO [STDOUT] (Thread-32) Notification of completed task 132 2012-08-22 12:32:06,017 INFO [STDOUT] (Thread-34) Notification of completed task 132 2012-08-22 12:32:06,025 INFO [STDOUT] (Thread-35) Notification of completed task 132 2012-08-22 12:32:06,033 INFO [STDOUT] (Thread-36) Notification of completed task 132 2012-08-22 12:32:06,042 INFO [STDOUT] (Thread-37) Notification of completed task 132 2012-08-22 12:32:06,049 INFO [STDOUT] (Thread-37) Notification of completed task 132 2012-08-22 12:32:06,056 INFO [STDOUT] (Thread-38) Notification of completed task 132 2012-08-22 12:32:06,063 INFO [STDOUT] (Thread-39) Notification of completed task 132 2012-08-22 12:32:06,069 INFO [STDOUT] (Thread-40) Notification of completed task 132 2012-08-22 12:32:06,076 INFO [STDOUT] (Thread-41) Notification of completed task 132 2012-08-22 12:32:06,082 INFO [STDOUT] (Thread-41) Notification of completed task 132 2012-08-22 12:32:05,985 INFO [STDOUT] (Thread-31) Notification of completed task 132 2012-08-22 12:32:05,998 ERROR [org.hibernate.event.def.AbstractFlushingEventListener] (Thread-31) Could not synchronize database state with session org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.persistence.processinstance.ProcessInstanceInfo#44] at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1782) ....... at org.jbpm.task.service.hornetq.CommandBasedHornetQWSHumanTaskHandler$GetCompletedTaskResponseHandler.execute(CommandBasedHornetQWSHumanTaskHandler.java:273)
