NPE when AbortWorkItem ---------------------- Key: JBRULES-2896 URL: https://issues.jboss.org/browse/JBRULES-2896 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.2.0.M1 Environment: JbossAS 5.1 MySQL 5.0.77 Reporter: Cristiano Nicolai Assignee: Kris Verlaenen Labels: drools5, drools_persistence Fix For: 5.2.0.M2 Attachments: 0001-AbortWorkItem-should-test-if-WorkItemInfo-inst-null-.patch AbortWorkItem method should test if WorkItemInfo inst null before merge. Basically is the same behaviour as completeWorkItem. I'm getting the following exception when a Work Item is aborted: 2011-02-10 16:52:37,282 ERROR [org.drools.persistence.SingleSessionCommandService] (NioProcessor-3) Could not commit session java.lang.IllegalArgumentException: attempt to create merge event with null entity at org.hibernate.event.MergeEvent.<init>(MergeEvent.java:60) at org.hibernate.event.MergeEvent.<init>(MergeEvent.java:43) at org.hibernate.impl.SessionImpl.merge(SessionImpl.java:690) at org.hibernate.impl.SessionImpl.merge(SessionImpl.java:694) at org.hibernate.ejb.AbstractEntityManagerImpl.merge(AbstractEntityManagerImpl.java:235) at org.drools.persistence.jpa.JpaPersistenceContext.merge(JpaPersistenceContext.java:49) at org.drools.persistence.jpa.processinstance.JPAWorkItemManager.abortWorkItem(JPAWorkItemManager.java:136) at org.drools.command.runtime.process.AbortWorkItemCommand.execute(AbortWorkItemCommand.java:56) at org.drools.command.runtime.process.AbortWorkItemCommand.execute(AbortWorkItemCommand.java:29) at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:295) at org.drools.command.impl.CommandBasedStatefulKnowledgeSession$1.abortWorkItem(CommandBasedStatefulKnowledgeSession.java:152) at org.jbpm.process.workitem.wsht.CommandBasedWSHumanTaskHandler$GetCompletedTaskResponseHandler.execute(CommandBasedWSHumanTaskHandler.java:245) at org.jbpm.task.service.TaskClientHandler.messageReceived(TaskClientHandler.java:81) at org.jbpm.task.service.mina.MinaTaskClientHandler.messageReceived(MinaTaskClientHandler.java:47)
