我的流程文件如下:

<?xml version="1.0" encoding="UTF-8"?>

<process-definition
  xmlns="urn:jbpm.org:jpdl-3.1"  name="test">
   <start-state name="start">
      <transition name="d11" to="decision1"></transition>
   </start-state>
   <decision name="decision1">
     <handler class="com.test.decision.D1Handler"/>   
      <transition name="t1" to="task1"></transition>
      <transition name="t2" to="task2"></transition>
   </decision>
   <task-node name="task1">
      <task name="task1">
          <assignment class="com.test.task.T1AssignmentHandler"></assignment>
      </task>
      <event type="node-leave">
         <action name="act1" class="com.test.action.Act1ActionHandler"></action>
      </event>
      <transition name="d21" to="decision2"></transition>
   </task-node>
   <task-node name="task2">
      <task name="task2">
          <assignment class="com.test.task.T2AssignmentHandler"></assignment>
      </task>
      <event type="node-leave">
         <action name="act2" class="com.test.action.Act2ActionHandler"></action>
      </event>
      <transition name="d22" to="decision2"></transition>
   </task-node>
   <decision name="decision2">
      <handler class="com.test.decision.D2Handler"/> 
      <transition name="e1" to="end"></transition>
      <transition name="d12" to="decision1"></transition>
   </decision>
   <end-state name="end"></end-state>
</process-definition>

流程流转
decision1->task1->decision2->decision1->task2->decision2->end

在前几步都没有问题
一直到->task2->decision2->end 完成task2时出现问题我完成task2的方法

如下


protected void t2Decide(boolean isApprove) {
System.out.println("T2审批TestProcessTest.t2Decide()=");
String userIdT2 = "userApprove2";
List list = ctx.getTaskMgmtSession().findTaskInstances(userIdT2);
Iterator it = list.iterator();
while (it.hasNext()) {
TaskInstance ti = (TaskInstance) it.next();
if (ti.getName().equals("task2") &&
(pi.getId() == ti.getTaskMgmtInstance().getProcessInstance().getId())) {
if (isApprove)
ti.end("d21");
else
ti.end("d21");
return;
}
}
}

在ti.end("d21");这一句出错,错误如下:

请教各位大侠  谢谢了  万分火急

ctx.getTaskMgmtSession().findTaskInstances(userIdT2);
中的ctx是否为executeContext?

是JbpmContext

终于有回应了

哈哈 自己搞定了

搞定了，怎么也不说说解决方法呢？
唉。。。。

想学习都不行

是低级错误,ti.end("d21")应该是ti.end("d22");

ctx是否为executeContext?
