[jboss-user] [jBPM] - jbpm 5.4.0 - NullPointerException completing workItem when using Spring local transactions and shared entity manager.

J Xmith [https://community.jboss.org/people/xmithj] created the discussion "jbpm 5.4.0 - NullPointerException completing workItem when using Spring local transactions and shared entity manager." To view the discussion, visit: https://community.jboss.org/message/789975#789975 -------------------------------------------------------------- I decided to give it a try to Spring local transactions and shared entity manager, so I changed my configuration as per user guide v5.4. I tested with a fairly simple business process with an asynchronous workItem that get completed after certain amount of time by a different thread. Everything went well until the scheduled timer tried to complete the workItem by calling:      ksession.getWorkItemManager().completeWorkItem(workItemId, resultMap); By executing this line, I am getting this exception: 2013-01-10 15:13:46,234 ERROR  [Timer-0] SingleSessionCommandService M[rollbackTransaction] --> Could not commit session java.lang.NullPointerException     at org.jbpm.workflow.instance.node.WorkItemNodeInstance.workItemCompleted(WorkItemNodeInstance.java:306)     at org.jbpm.workflow.instance.node.WorkItemNodeInstance.signalEvent(WorkItemNodeInstance.java:285)     at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:342)     at org.drools.persistence.jpa.processinstance.JPAWorkItemManager.completeWorkItem(JPAWorkItemManager.java:121)     at org.drools.command.runtime.process.CompleteWorkItemCommand.execute(CompleteWorkItemCommand.java:69)     at org.drools.command.runtime.process.CompleteWorkItemCommand.execute(CompleteWorkItemCommand.java:32)     at org.drools.command.impl.DefaultCommandService.execute(DefaultCommandService.java:36)     at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:373)     at org.drools.command.impl.CommandBasedStatefulKnowledgeSession$1.completeWorkItem(CommandBasedStatefulKnowledgeSession.java:150) The passed workItemId is correct (the expected one). The same test runs successfully when configuring for JTA transaction management. Should I create a Jira issue for this?
