This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
Jay, Are you looking to get the ids or descriptions in the options? UnitOfIssue.values() will give you a collection of the ids.
I can't think of a way to get a collection of descriptions without writing some code in the action. It isn't hard code to write of course. Just a loop to build the collection and then stick it in the request/session.
