Issue with multi instance parallel user task and conditional sequence flows

roopa_thakkar — Tue, 19 Dec 2017 05:08:00 GMT

For a multi instance parallel user task I have configured conditions on all outgoing sequence flows. When the task gets complete, Activiti engine is marking all its subsequent task as pending even if condition on only one flow was true.E.g. Task A goes to task B and task C and conditions are defined

Could you please post an example bpmn file which shows your use case description? Btw, 5.16 is quite an old version, I suggest testing your process either in the latest 5.x branch (5.22.0) or 6.0.0 branch just to make sure you are not hitting a bug which may be fixed in one of the newer versions!

Hi,

I am uploading the templates which I have used. Template "TestBpmnprocess.bpmn20.xml" is the one which has issue while template "TestBpmnprocessUpdated.bpmn20.xml" works when I change the "isSequential" flag from "multiInstanceLoopCharacteristics" node as true.

Yes, the Activiti engine I am using is not latest but could not switch to it right away as we have developed quite a bit on this version. Eventually will move to the latest version.

Hi Roopa,

It's most likely a bug with the multi-instance. Do you mind creating a issue on Activiti project with a reference to this post or even making a contribution with a fix!!

The reason why this might have gone unnoticed is that, people typically will have a gateway in such situation. For example, if you add an exclusive gateway right after Task 1 (as shown below), it works fine for parallel as well.

Hope this helps

Hi Joseph,

Thanks for your reply. Yes I am aware that if a gateway is added it works and that is the work around I have used. Yes, I will create an issue on Activiti project.

Thanks.

Joseph do you have link to the system where I can create issue on Activiti project? If yes can you please share?
