We activated the "Jira Policy" and "Jira Ticket Checks" section of Control Freak on repositories which didn't have this section enabled yet, and in some of the repositories the HEAD commit does not satisfy these conditions.
If a developer now tries pushing a new branch (with or without commits), Control Freak will complain that the commit which is the base of the branch does not reference a Jira Ticket, or references a Jira Ticket which is already in status "Done".
We were able to get it to work properly on a brand new repository, but surely there must be a way to make use of this on an existing one?
