ExecutionListener was excuted 2 times, why?

[wliang_bj]

I encouter a question.

I defined a class named ExecutionCommentListner implements ExecutionListener, and defined it's event="end"; like below:

public class ExecutionCommentListner implements ExecutionListener {

   private static final long serialVersionUID = -6014971966749562667L;

   public void notify(DelegateExecution exec) throws Exception {
      // TODO Auto-generated method stub
      System.out.println(exec.getVariable("approved"));
      System.out.println(exec.getVariable("comment"));
      System.out.println(exec.getCurrentActivityName());
   }

}

when I complete the task node, I find ExecutionCommentListner was executed 2 times;

I got :

true
hello
null
true
hello
UserTask1

is this a bug , or did I do something wrong? BTW my version is 5.12

How does your BPMN XML look like?

[wliang_bj]

    <userTask id="directorAudit" name="ManagerAudit" activiti:assignee="${assignee}" activiti:formKey="audit.form">
      <documentation>${applyUserName} want to apply ${days} days and ${type}(${startTime}to${endTime}) holiday</documentation>
      <extensionElements>
        <activiti:executionListener event="end" class="cn.com.etib.iacframework.activiti.service.ExecutionCommentListner"></activiti:executionListener>
      </extensionElements>
      <multiInstanceLoopCharacteristics isSequential="false" activiti:collection="${security.getDirectorsByStarter(applier)}" activiti:elementVariable="assignee"></multiInstanceLoopCharacteristics>
    </userTask>

Above is a period of my bpm description, did I do anything wrong?

It seems that you have more than one instance of the <code>directorAudit</code> activity - depending on the content of the <code>security.getDirectorsByStarter(applier)</code> you receive messages (log records) for each activity instance.

[wliang_bj]

${security.getDirectorsByStarter(applier)} has only one result.
My situation is when I use ExecutionListner to listen to the task finish My listener was executed twoice, but when I change it to TaskListener, My listener was executed only once.

I have writer ExecutionCommentListner implements ExecutionListener and TaskCommentListner implements TaskListener to test the different situation.

I'm guessing you're receiving one execution listener event for the task-instance being completed and another event when the whole multi-instance scope is completed… So in case you have a Munti-instance with 5 instances, you're execution-listener will be called 6 times. Can you validate this behavior?
