      <process-definition name="PssDemoFlow">
 <start-state name="start">
 <transition name="trDetermineWfType" to="DetermineWfType"></transition>
 </start-state>
 <decision name="DetermineWfType">
 <event type="node-enter">
 <action name="DetermineWorkflowType" class="pss.jbpm.demo.DetermineWfType">
 <message>this is test</message>
 </action>
 </event>
 <transition name="trSendNotifications" to="SendNotifications"></transition>
 <transition name="trNode1" to="node1"></transition>
 </decision>
 <task-node name="SendNotifications" create-tasks="false">
 <task name="SendNtfTask">
 <assignment class="pss.jbpm.demo.NtfAssignmentHandler"/>
 </task>
 <event type="node-enter">
 <action name="CreateNotifications" class="org.jbpm.taskmgmt.exe.CreateNotifications">
 <message>this is a test123</message>
 </action>
 </event>
 <transition name="trEnd1" to="end1"></transition>
 </task-node>
 <node name="node1">
 <event type="node-enter">
 <action name="NodeAction" class="pss.jbpm.demo.myaction"></action>
 </event>
 <transition name="trEnd2" to="end1"></transition>
 </node>
 <end-state name="end1">
 <event type="node-leave">
 <action name="endWfInstance" class="pss.jbpm.demo.endWfInstance"></action>
 </event>
 </end-state>

</process-definition>



      In my action i am hard coding transition to have flow like
      start->DetermineWfType-> node1>end1

      in end1 node-leave action, I am ending the process by using this code 

      public void execute(ExecutionContext context) throws Exception {

 ProcessInstance processInstance = context.getProcessInstance();
 Collection listTasks = processInstance.getTaskMgmtInstance().getTaskInstances();
 if (listTasks != null && listTasks.size()>0) {
 for (Iterator iter = listTasks.iterator(); iter.hasNext(); ) {
 TaskInstance ti = (TaskInstance) iter.next();
 if (!ti.hasEnded()) {
 ti.setEnd(new java.util.Date());

 Token tk = ti.getToken();
 tk.end();

 }
 }
 }
 if (!processInstance.hasEnded()) {
 processInstance.end();

 }
 }



      everthing works fine and flow get executed as I wanted. But after it reached at the end, it executing some of the node even after instance is ended also it traversing to task node.

      I am totally confused
      1. why some node is executing twice
      2. Why it traversing to task-node even after i have ended instance

      this is my debug log from console
