Different order of execution of the tasks: activiti bug?

[udoderk]

Hi all,
I model the following business process. This business process includes the following steps:
1 - "Start" User Task.
2 - "Make decision" User Task: the user specifies whether "yes" path or "No" path must be chosen.
3 - If "Yes" path is selected, then is "Bugfix" User Task runs.

4 - Whether "Yes" or "No" is selected, "Checkpoint" User Task must be allways running.
5 - "End" User Task must be running.

I have tried to model this process firstly without the inclusive gateway. If  inclusive gateway would be used, so it would be look like the diagram as follows:

Note, the generation of BPMN20 XML for Activiti 5.10 is based on the existing data from another application. This another application is used to model business process too.

My problem is that i have for same business process two generation-cases and a different order of execution of the tasks in Activiti Explorer depending on how I design the business process in another application.

Therefore, I would like to know the rules by which the order is the flow of tasks defined.

Details:

If i use the following xml, and select "No" checkbox within "Make decision" user task ,  so the "Checkpoint" user task with number 4 occurs before of the user task "Bugfix" number 3 (not correct !):

I thank you for the some ideas and help!

how do you get the image in there? I tried everything….

i use just the "img" tag. Before i have retrieved the image url using firefox context menu entry.

I do not understand the 'shift to bottom'

The "Checkpint" is to be moved to bottom corner to other (virtual) swinlane on your image. But it is absolutely not important.

I used that to… did not work for me… Weird… Did you do [img=url][/img] or with quotes around the url or the url between the tags or…

PLEAAAASSSEEE 😉

i use it just with image tag: [_img_]imageurl[_/img_]
In example "_" is quasi escape operator;-)
