Problem:
In Moodle 4.2, an unintended change in behaviour occurred when locking
and unlocking grade items. Previously, in Moodle 4.1, locking a grade
item and then subsequently unlocking the grade item left specific grades
for students still locked if they were being locked individually.
However, in Moodle 4.2, the unintended change caused the individual
grades to be unlocked along with the grade item.
Solution:
To address this issue, I modified the set_locked calls in action.php to
pass the cascade parameter as false. Now, when locking or unlocking a
grade item, only the grade item itself is affected, leaving individual
grades unchanged. I have also modified the locking behaviour in the
grade_category class. So, similarly, when locking or unlocking a grade
category, the change applies only to the grade items and grade
categories within the category, without expanding to individual grades.
Explanation:
By making this change, we ensure that the locking mechanism behaves as
expected, providing a consistent and desirable user experience. Locking
and unlocking a grade item or category will no longer inadvertently
affect individual grades, preserving their locked status and avoiding
loss of data when unlocking a grade item associated with the total mark
of a category.
This is a followup to MDL-18301. That fix missed the following points:
1. On the edit categories and items screens, all items had an eye-con to
control the visibility, even if the visibility was controlled by the
module.
2. Changing the visibility of a grade category change the visibility of
all items within it, even if the visibility was controlled by the
module.
3. The quiz ingored $cm->visible when controlling whether its grade item
was visible.
