[jboss-user] [JBoss jBPM] - Cancel a process in a repeated action

i'm starting the execution of an action 5 seconds after entering a task node. this action repeatedly checks a state in a third party application and eventually shall cancel the whole process instance. i'm trying to do this by using this code: CancelProcessInstanceCommand cpic = new CancelProcessInstanceCommand(task.getProcessInstance().getId()); | cpic.setCancelSubProcesses(true); | CommandServiceImpl csi = new CommandServiceImpl(jbpmConfiguration); | csi.execute(cpic); i get the following error (running with postgreSQL on apache tomcat): 12:38:46,520 ERROR [168.0.18:1] JobExecutorThread : exception in job executor thread. waiting 2500 milliseconds | org.jbpm.JbpmException: problem closing services {persistence=org.jbpm.persistence.JbpmPersistenceException: hibernate commit failed} | at org.jbpm.svc.Services.close(Services.java:235) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | at org.jbpm.job.executor.JobExecutorThread.executeJob(JobExecutorThread.java:181) | at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:62) | Caused by: org.jbpm.persistence.JbpmPersistenceException: hibernate commit failed | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:216) | at org.jbpm.svc.Services.close(Services.java:222) | ... 3 more | Caused by: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.job.Timer#683] | 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:253) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:211) | ... 4 more | | i've read about the concept of executing the commands asynchronously but it seems the CommandServiceImpl executes the CancelProcessInstanceCommand immediately (when my action, called out of the JobExecutor/Timer is still active)... i'm not sure how to solve this and haven't found a thread or solution in this forum yet that seem to fit my problem. | | thank you very much, | volker View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059573#...
