When trying to generate a grade report for assignments with collaborative group submissions I don't get any students in the report list. I have repeated this on version 10, 11 and trunk.
Steps to reproduce:
1. As teacher create a new site
2. Add 1 student to site
3. Create new group and add student
4. Create Assignment and check "Is this a collaborative group submission?"
5. Login as student and submit the assignment
6. Login as teacher
7. Go to assignment list and grade the submission
8. Try to generate Grade Report
Expected result: List with the student
I have searched Sakai Jira but have not found any reports on this which I found strange for this basic fault. Or is this not supposed to work this way?
