grade_minmaxtouse not respected for overridden categories

Prerequisites A course with a teacher and a two students (I'll call them student A and student B) Additional grade category aggregation types enabled: "Site administration" > "Grades" > "Grade category settings" > select all the items under "Available aggregation types" A gradebook with a category item with aggregation set to highest grade. Set this up at "Course administration" > "Gradebook setup". Just enter the name, leave everything else at defaults. 2 grade items in the grade category. Again, just enter a name, leave everything else at the default setting (except the category, set that to the category you just made). Testing The following is all done as the teacher: Navigate to "Course administration" > "Grades", then "Grade administration" > "Single view" Select student A and award them a grade of 60 for one grade item and 70 for another. Select student B and award them a grade of 60 for one grade item and 70 for another. Navigate to "Grade administration" > "User report" and view the report for student A. Verify the their total for the category is 70% View the report for student B and verify the total for the category is also 70% Navigate to "Setup" > "Gradebook setup" and edit the grade category. Under "Category total" verify there is no mention of rescaling. Change the maximum grade to 150. Check the user report for student A and student B. Verify they both still have a grade of 70% for the category. Navigate to "Grade administration" > "Single view" and select student A. Check the override box for the grade category and award them a grade of 150. Verify on the user report that student A now has a mark of 100% for the category. Navigate to "Setup" > "Gradebook setup" and edit the grade category. Expand the "Category total" section and verify a message is displayed explaining that grades have already been awarded and a decision must be made. Try to change the min/max without selecting whether to rescale. Verify you get an error. Choose to rescale the grades, and update the maximum to be 200 View the user report for student A and verify that they still have a mark of 100% View the user report for student B and verify that they still have a mark of 70% Change the max for the category to be 300, this time choosing not to rescale. Check the user report for student A and verify that their mark is still 100% and the rande for the category is still 0-200 Check the user for student B and verify that they have a mark of 70% for the category and the range is 0-300 Bonus: Repeat the above using different aggregation methods if you want :]
