We recently upgraded to 2.2 from 1.9 and a teacher has reported an issue with the Gradebook. In the previous version he could hide an assignment in the gradebook by hiding it in his topic area and then setting the gradebook options to "Do not show" hidden items. Since converting to 2.2 that feature isn't working and I can't find a tracker issue on it.
Another interesting item is as the Admin users, when I turn editing on in the gradebook, I see all of the edit icons including the show/hide icon.
If I log in as a teacher, the edit icons are missing.
I looked at permission for the teacher role and it has allow for all grading activities. What am I missing?
