      Description

      Unfortuantely, we don't have a way to reproduce this probem, but occasionally, when a student takes a Samigo test, they will answer a question correctly, but the UI shows a score of 0.

      So far, we have seen this with samigo question types:

      • Multiple Choice Single Correct
      • Matching

      but I haven't checked every instance of the issue, so there could be other types affected

      Also, we asked one of the students if they saw any errors or had problems while taking the test she said

      Yes i experienced in slow loading a couple of times when I took the quizes. I had to reload it a couple of times.

      Checking the database, the "autoscore" value for the answer is set to NULL (see the last row in this query:

      mysql> select SUBMITTEDDATE, PUBLISHEDANSWERID, RATIONALE, ANSWERTEXT, AUTOSCORE, OVERRIDESCORE, comments from sam_itemgrading_t where assessmentgradingid = '2364664' order by submitteddate;

      Checking for other instances of this issue, we found 34 since upgrading to Sakai 11.4 and none before (not since 2010 with an early version of Sakai 2.x, but that could be due to something else?):
