Comment 2 for bug 1258939

I get the same behaviour if I choose 'Attendance' as the score system. First, it shouldn't be there, and second it should not fail so badly.

To reset the scoresystem, go to the gradebook, append '?scoresystem' to the end of the location, and press Enter. For example,

http://localhost:7080/schoolyears/1/912/sections/2/activities/Worksheet/gradebook?scoresystem
