This picker has a JavaScript "combobox" behavior added to it, so the editor can add new roles to the list at whim. But the output is an array. Does this invalidate my use of a helper method? Or am I thinking too much about the label "helper" here?

To me that looks more like something that should be called in the
controller and go into an @ variable for use in the view. The general
rule is setup data in the controller and display it in the view. The
method itself could go in the Role model or in a module in lib
