I recognized an interesting behavior in cuba bpm process cancellation.
I am not sure if this is how it supposed to work.
When I have an active process instance and I’d like to cancel it on the BPM -> Process Instances module, then the Comment form appears. This comment is required if I’d like to click on the OK button, yet if I choose the Cancel button, it stops the process and I don’t need to specify a comment.
This may be a bug, or this is how it supposed to work?
