To view the discussion, visit: https://community.jboss.org/message/780307#780307 -------------------------------------------------------------- Hi JBPM, In my case,it's a approve process used JBPM5.3! Several days ago,i build a example no using JPA&JTA.And i could pass a result (just "agree" and "reject") value to a human task node while a want to complete this task by the following code.      SyncWSHumanTaskHandler s = new SyncWSHumanTaskHandler();      Map map = new HashMap();      data.put("result", "agree");      ContentData contentData = ContentMarshallerHelper.marshal(data,s.getMarshallerContext(), null);      sTaskService.complete(taskId, userId, contentData); and this human task's next node is a diverge gateway, it will used the mvel (like return result == "reject") to decide which sub switch way to go!Several days ago it could go easily without using JPA&JTA. Today ,i add the JPA&JTA in my case.But a WorkflowRuntimeException was caught! anyone can help me? org.jbpm.workflow.instance.WorkflowRuntimeException: [com.sogou.ka.contract:1 - Gateway:4] -- XOR split could not find at least one valid outgoing connection for split Gateway at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:130) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerNodeInstance(NodeInstanceImpl.java:205) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerCompleted(NodeInstanceImpl.java:164) at org.jbpm.workflow.instance.impl.ExtendedNodeInstanceImpl.triggerCompleted(ExtendedNodeInstanceImpl.java:47) at org.jbpm.workflow.instance.node.StateBasedNodeInstance.triggerCompleted(StateBasedNodeInstance.java:162) at org.jbpm.workflow.instance.node.StateBasedNodeInstance.triggerCompleted(StateBasedNodeInstance.java:143) at org.jbpm.workflow.instance.node.WorkItemNodeInstance.triggerCompleted(WorkItemNodeInstance.java:239) at org.jbpm.workflow.instance.node.HumanTaskNodeInstance.triggerCompleted(HumanTaskNodeInstance.java:90) at org.jbpm.workflow.instance.node.WorkItemNodeInstance.workItemCompleted(WorkItemNodeInstance.java:301) at org.jbpm.workflow.instance.node.WorkItemNodeInstance.signalEvent(WorkItemNodeInstance.java:277) at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:326) 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:367) at org.drools.command.impl.CommandBasedStatefulKnowledgeSession$1.completeWorkItem(CommandBasedStatefulKnowledgeSession.java:150) at org.jbpm.task.service.hornetq.CommandBasedHornetQWSHumanTaskHandler$GetResultContentResponseHandler.execute(CommandBasedHornetQWSHumanTaskHandler.java:308) at org.jbpm.task.service.TaskClientHandler.messageReceived(TaskClientHandler.java:153) at org.jbpm.task.service.hornetq.HornetQTaskClientHandler.messageReceived(HornetQTaskClientHandler.java:56) at org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1.run(HornetQTaskClientConnector.java:120) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.IllegalArgumentException: XOR split could not find at least one valid outgoing connection for split Gateway at org.jbpm.workflow.instance.node.SplitInstance.internalTrigger(SplitInstance.java:98) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:124) ... 21 more 48   06/12 16:40:48,122[Thread-14] ERROR service.hornetq.HornetQTaskClientConnector.run  - [com.sogou.ka.contract:1 - Gateway:4] -- XOR split could not find at least one valid outgoing connection for split Gateway Thanks and Best Regards! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/780307#780307] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
