Regarding multi instance behaviour

Hello,

I am trying to run a multi instance sequential behaviour for my service task. I have set the loop counter to 5.

My listener receives a start event from  activiti for each iteration i.e, in this case it receives 5 start events.

But , I get only one end event . Does this single end event mark the completion of all the iterations ?

Also, in the case of failure in any one of the iteration ,  how will this end happen?

It would be great if someone could clarify on this.


Thanks

An error in a multi-instance is handled the same way as it would occur in a simple service-task: transaction is rolled back and process is back in the state it first was.

I assume you're referring to an "execution-listener" on the multi-instance serviceTask? AFAIK, there are called for every execution of the loop:

Take for example org.activiti.engine.impl.bpmn.behavior.SequentialMultiInstanceBehavior
<br> /**<br>&nbsp;&nbsp; * Called when the wrapped {@link ActivityBehavior} calls the <br>&nbsp;&nbsp; * {@link AbstractBpmnActivityBehavior#leave(ActivityExecution)} method.<br>&nbsp;&nbsp; * Handles the completion of one instance, and executes the logic for the sequential behavior.&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp; */<br>&nbsp; public void leave(ActivityExecution execution) {<br>&nbsp;&nbsp;&nbsp; callActivityEndListeners(execution);<br>
If you are indeed referring to a execution-listener on the service-task, and you only see the end-execution-listeners executed once, please comment and perhaps include the bpmn20.xml file.
