When trying to manually grade [Quiz] essay question attempts, if attempts are sorted by the first letter of students' first or last names (the initialbars) and the sorting results are empty, links to see the original attempts or other sorting options will then become unavailable. From this point, there is no way to see view and manually grade anymore essay question attempts unless the instructor logout first and then log back in.
Steps to reproduce
1. Login as a teacher to a course
2. View a quiz with essay questions (that requires "manual grading")
3. Click on Results tab
4. Click on Manual Grading
5. Click on letter link (First name, Surname) to sort the attempts, choosing a letter not represented in the attempts
The links to view all or sorted essay question attempts do not appear. The page only shows the message "There are no attempts to show". There is no way to navigate and view anymore essay question attempts. See screenshots.
My temporary workaround is to change the /mod/quiz/report/grading/report.php at around line #251, to change the original
I'm sure that there is a better way to do this. Thoughts or comments? Thanks!
