A) To be executed before-patch (last weekly release, without this patch applied). 0. As admin or editing teacher... 1. Create a course (better with some existing enrolled users ) and create an assignment 2. Go to the course and then go to the All Participants. then click the edit button on the top right and find the Groups 3. Next, create a group, then auto-create groups and add a new grouping and remember this newly added group. 4. Go back to the assignment created, edit it and then set the due date. (remember it, COURSEDUEDATE) 5. Go to group override and set another due date for the group created (remember it, GROUPDUEDATE) 6. Go back to assignment view page [http://localhost/mod/assign/view.php?id=[assignmentid]&group=[groupid]] and select separate groups select box between options "All Participants" and "Group" we created in step 3. We should see there is no different due date even we have set another due date in group override. COURSEDUEDATE is displayed. that's the bug. B) To be executed after-patch (current branch checkout applied) 7 Go back to assignment view page in step 6, if you are a user who can view grades, should be able to switch groups and see the different due date (GROUPDUEDATE ) for the group. That's the fix
