When displaying users by Role in Roster2, the sorting breaks. Steps to reproduce:
- Login to Sakai
- Access a course site with multiple enrolled users
- Click on the Roster tool in the left navigation area
- Notice the ordering
- Select the Student role (or any other that has multiple users)
Expected Result : The roster tool lists only Student roles and keeps them in alphabetical order
Actual Result: The tool displays only the Student roles, but order looks completely random. Not ordered by user_id, email, or name.
