I'm trying to make a script listener to spit out a comment every time the fixVersion is changed. Ideally, I want the comment to be something like "Old Version: v13, New Version: v14". Where I'm having is trouble is this "def change = event?.getChangeLog()?.getRelated("ChildChangeItem")?.find {it.field == "Fix Version/s"}" always outputs null to change.oldline. I can't figure out how to get the previous fixversion after the change.
Thanks!
