Parallel gateway executes mores executions then it should

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi,
we use parallel gateway to split a process into two parallel executions and then join them like this:
[img]http://unknown.cz/actis/parGWProblem.jpg[/img]
We implemented our own BpmnParseListener and added a start and end listeners to all activities.
These listeners log all events like this:

Activity start: vyhodnoceniTemplate (execId=102533; procId=102533; type=serviceTask)‍

Problem is that with above scenario the parallelGateway1 executes three executions:

Activity start: parallelgateway1 (execId=102533; procId=102533; type=parallelGateway)
Activity end: parallelgateway1 (execId=102554)
..execution of other tasks..
Activity end: parallelgateway1 (execId=102555)
..execution of other tasks..
Activity end: parallelgateway1 (execId=102556)
Activity start: exclusivegateway27 (execId=102556; procId=102533; type=exclusiveGateway)‍‍‍‍‍‍‍

Strange thing is that the third execution jumps immediately to exclusivegateway27 which the one after callActivity1.
This problem started to occur “just like that”. Without us changing a single line of code.
We use Activiti engine 5.8 and all processes are created in designer 5.8.

Is there any other info you need me to provide?

Hi,

It's very difficult to respond to this without the full process definition.
But what I see from the attached images is that you only have one incoming sequence flow in the 2nd parallel gateway. Then that gateway just executes, because only one sequence flow is incoming.

Best regards,
