      Hide

      Setup:

      1. Create a course and enroll 4 students, "A", "B", "C", and "D"
      2. To make life easier, you will want to open multiple browsers (or private mode windows) so you are logged in as all 4 students and a teacher/admin (called teacher or teacher 1 in these instructions)

      Normal flows

      This first block of steps tests these flows:

      Assign 1
      A - No Submission > reopen > Submission > grade
      B - No Submission > grade > reopen > Submission > grade
      C - Submission > reopen > Submission > grade
      D - Submission > grade > reopen > Submission > grade

      1. As the teacher, make a new assignment, "Assign 1", set "Attempts reopened" to Manually under "Submission settings"
      2. As students C and D, add new submission content
      3. As the teacher, go to the submission grading table and enable quick grading
      4. Give student B a grade of 40 and student D 60 and click "Save all quick grading changes"
      5. Confirm that no errors are reported, and users B and D have the correct grades listed
      6. Select the checkboxes next to all students, and from the menu "With selected..." select "Allow another attempt", then click go, and confirm the popup dialog
      7. As all 4 students add new sumissions
      8. As the teacher, reload the grading table view, and give student A a grade of 31, student B 41, student C 51, D 61 and click "Save all quick grading changes"
      9. Confirm that no errors are reported and all 4 students have the correct grades

      Collision and resumed flows

      Description

      Whenever you allow another attempt for a submission, it is impossible to save quick grades due to the following error message: "The grades were not saved because someone has modified one or more records more recently than when you loaded the page."

      Steps to reproduce:
      1. Create a new assign with some amount of allowed attempts.
      2. Submit as a student.
      3. Make sure Quick grading is turned on.
      4. Grade the assignment (say, Fx in Bologna Scale or whatever) so the student is aware that he got a half-passing grade.
      5. Allow another attempt so the student can improve his/her grade
      6. Ensure that 'Save all quick grading changes' throws the error mentioned above no matter which one will be graded.

      Problem:
      Line 5298 of assign/locallib.php. $modified->lastmodified gets nullified once you allow a new attempt, therefore an error is thrown.

                      if ((int)$current->lastmodified > (int)$modified->lastmodified) {
      		 
                          // Error - record has been modified since viewing the page.
      		 
                          return get_string('errorrecordmodified', 'assign');
      		 
                      } else {
      		 
                          $modifiedusers[$modified->userid] = $modified;
      		 
                      }
