it's been very frustrating to modify the workflow in jira for a project to make not only the done status generates a resolution, but also cancelled status for a a project, I see tutorials and everybody talks about post functions, something I can't see when I edit the workflow, The only option I see is add transtiions and 'rules'. I set cancelled as a (done) status (green hightlighted), and set a rule to change from all other status to cancelled and affect end date, but it's not working. When I use the jira API REST to bring that data, the problem continues, only done tickets shows a resolution date, cancelled shows 'none'
