Affects Version/s: 11.4, 11.5 [Tentative], 19.0
Fix Version/s: None
Component/s: Tests & Quizzes (Samigo)
The original error report the instructor received from his TA:
When grading tests in the "Tests & Quizzes" view with more than one question, the entered comments and points seem to carry over when changing the view to a different Übung.
This behavior only occurs when the second part of the question is selected. Selecting the first part, switching the Übung and then selecting the second part again seems to work.
This sounds very similar to
SAK-36177 Scores -> View by group adjustment screen not resetting properly / possible to set incorrect grades"
..only it affects the "Questions" view instead of the "Grades" view:
If you use the "Questions" tab and switch between the "View for" e.g Section01 and Section02, then whatever values have been entered for points and comments in row "#n" when viewing Section01 will still appear in row "#n" after switching to Section02 - only row "#n" belongs to a different student now.
(See attached screenshots; "Übung" == "Section")
This happened on 11.4, but I could reproduce it on my 11.x development installation and also a master (13-snapshot) from one or two weeks ago, so it's a pretty good bet that it's also present in 12.x.
