nodes are executed mutiple times

[alal007]

this is my sample definition
code:
<process-definition name="PssDemoFlow">
<start-state name="start">

</start-state>



this is test





<task-node name="SendNotifications" create-tasks="false">





this is a test123



</task-node>






<end-state name="end1">



</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

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();
// log.debug("token " + tk.getName() + " has ended");
}
}
}
if (!processInstance.hasEnded()) {
processInstance.end();
}
}


everthing works fine and flow get executed as I wanted. But after it reached at then end, it executing some of teh 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

I don't know why my definition has not come correctly earlier

<process-definition name="PssDemoFlow">
<start-state name="start">

</start-state>



this is test





<task-node name="SendNotifications" create-tasks="false">





this is a test123



</task-node>






<end-state name="end1">



</end-state>
