I want my "Fix version" field for issues/bugs to be a required field so that it needs to be filled in for creation. At the same time, if this issue/bug has a parent, I would like the "Fix version" field to inherit/be pre-populated with the same value as the parent so that the user can just review and see that it is the right version and click "ok" for those cases.
I managed to make the "Fix version" field required. But I can't seem to figure out how to have it pre-set with the parent's value. I tried adding a "post-function" action in the task workflow (which doesn't seem to get triggered until after the creation screen - at which point, the user already manually filled it out).
