We have custom user fields (ie 'Business Analyst', 'Developer', etc.) in JIRA, and we would like to be able to send an email to those users when they are assigned to one of those fields. I have looked over the JIRA wiki, and could not find a way to do this.
I know this is possible with the 'Issue Assigned' event, but in this case, the JIRA is not being assigned, since we are using custom fields.
Is this at all possible?
