I want to require a custom field be filled out - but only on Epics, AND only when the epic transitions to a specific status (from any status).
I scanned quickly, and found this post, but it doesn't mention the transition piece, which is key for what I'm looking to do.
So for clarity, I'm looking for the following:
1) Epic issue is created (custom field is NOT required).
2) Epic issue goes from Open to In Progress status (custom field is NOT required)
3) Epic goes from In Progress to Testing status - custom field IS required.
4) Epic issue goes from Testing to Complete (custom field is NOT required, but it had already been filled out).
Thanks in advance!
