Hi, I have a problem with the execution of an action for my timers. I am using JBPM 3.2.2 with Tomcat and try to execute a process with a timer on 2 tasks in a fork.
The part of the process which give me troubles is the following : | <fork name="fork1"> | <transition name="To client" to="Client validation"></transition> | <transition name="To broker" to="Broker validation"></transition> | </fork> | <task-node name="Client validation"> | <task name="client complete and validate informations" swimlane="client"> | <timer name="reminder1" duedate="30 seconds"> | <action name="Send a time-out notice for client" class="common.processhandlers.DueDateHandler"></action> | </timer> | </task> | <transition name="Client informations completed" to="join1"></transition> | </task-node> | <task-node name="Broker validation"> | <task name="broker complete and validate informations" swimlane="broker"> | <timer name="reminder2" duedate="30 seconds"> | <action name="Send a time-out notice for broker" class="common.processhandlers.DueDateHandler"></action> | </timer> | </task> | <transition name="Broker informations completed" to="join1"></transition> | </task-node> | <join name="join1"> | <transition name="All informations available" to="end"></transition> | </join> | The class DueDateHandler i try to execute in both timer is in the sources of the web application executing the process and do nothing but displaying a message. When i try to execute this process and the duedate for the timers expire, i get the following Error : | ERROR - def.AbstractFlushingEventListener - 301 - 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.job.Timer#21383] | at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1765) | at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2407) | at org.hibernate.persister.entity.AbstractEntityPersister.updateOrInsert(AbstractEntityPersister.java:2307) | at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2607) | at org.hibernate.action.EntityUpdateAction.execute(EntityUpdateAction.java:92) | at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:234) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:142) | at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:298) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) | at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) | at org.jbpm.persistence.db.DbPersistenceService.commit(DbPersistenceService.java:256) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:214) | at org.jbpm.svc.Services.close(Services.java:225) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | at org.jbpm.job.executor.JobExecutorThread.acquireJobs(JobExecutorThread.java:144) | at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:58) | INFO -
