I would like to show a transition on an issue only if the current user belongs to the group selected in the group picker field on that issue.
For example, the group picker on the current issue is set to "Group A." If the current user belongs to the group called Group A, show the transition. If the current user is not in the group, hide the transition. The group picker may be set to Group A, Group B, Group C, etc. so it cannot be a static string in the condition.
I have not used Groovy scripting yet, but DO have Script Runner installed. Just not sure how to write anything in Groovy.
In short terms, I need to show my 'Assign To Me' transition on an issue if the current user is in the same group as the group picker value.
