Limit Fix Version to one value

[Alex Christensen]

I am trying to limit the user's input into Fix Version/s to only one value. I can do this easily in a validator as part of the workflow using ScriptRunner, but I'm having a lot of trouble even coming up with an idea of how to do this using a script listener in case a user makes inline changes or edits to an issue. Is there a way I can make the Fix Version/s field have a validator as a script listener?

You can configure the mailhandler in such a way that it will create user account whenever the originating mail address is not related to an existing user on your instance. See this page, and in particular the section on Mail Handlers

Thanks. As I understand this the tester send an ordinary email to the mail handler address and that results in that tester being added to the user database. Correct?

Might there be a template for aggragating testers?
