Specifying the incompatible transition
JIRA does not keep a track of the actual transitions (or workflow actions) but only of the changes in the status of an issue. So, it is impossible to distinguish between two transitions that share the same source and destination statuses. Therefore, this condition requires that you specify transitions in the form of a destination status and a source status (or Any for all transitions leading to the destination status).
When you add set this condition on a transition, the add-on checks whether the current user has triggered any transitions between the specified From Status and To Status. If a transition has been triggered between the two statuses, then the transition on which the condition is configured will be hidden from the user.
