End event triggered on non-canceling boundary timer?

[jhahn]

If there's a boundary timer with execution listener for event end, is it expected behavior that a non-canceling boundary timer will trigger the event end? So I have a receive task with a non-canceling timer with 30s timer. After 30s, it will execute the

<activiti:executionListener event="end" expression="${execution.setVariable(&quot;test&quot;, true)}"></activiti:executionListener>

Is this expected behavior? I expected it to not trigger since non-canceling timer doesn't really end the receive task?




Also, I'm a little confused on the documentation for execution listener. It says for event="start", it will NOTIFY the execution listener when it starts but only EXECUTE/CALL the notify function when an end event occurs. Then it says the 3rd execution listener (event="end") in that example will be CALLED when it "ends".

Is notify and call different? If event="start" and event="end" will both only be actually called when end event occurs, what's the difference?




Anyway, here is the test process for the first question.

Can you share the exact BPMN XML?
When the receive task has an execution listener for the end event, I would expect it not to be triggered when there's a boundary event attached that doesn't cancel the activity.

Whoops, I didn't put it in code block so it got erased. Anyway, just a simple case. After 30Seconds, it executes the expression although the receiveTask hasn't ended.

Then I think there is a bug here, that the event is thrown even when it's cancelActivity=false.

Could you create a jira issue (so you and us can follow up): https://activiti.atlassian.net/secure/Dashboard.jspa

Created issue here
https://activiti.atlassian.net/browse/ACT-3998

Marked it as "high" since it seems like a common basic use case that's not working as intended…
