Hello to All!
We updated to Moodle version 3.1
And now we have problems with Calculated multichoice question. This problem is opening for Moodle 2.5.4, 2.6.1 (https://tracker.moodle.org/browse/MDL-44267)
For example we have a Calculated multichoice question with Multiple tries
Question 1
Choices are:
={a} (grade +100%)
=2*{a} (grade -50%)
Hint 1: try one more
Penalty for each incorrect try: 33,3333%
If student will check both choices, there will be an error:
Coding error detected, it must be fixed by a programmer: PHP catchable fatal error
Error code: codingerror
- line 425 of /lib/setuplib.php: coding_exception thrown
- line 475 of /question/type/multichoice/question.php: call to default_error_handler()
- line 488 of /question/type/multichoice/question.php: call to qtype_multichoice_multi_question->disable_hint_settings_when_too_many_selected()

- line 449 of /question/engine/questionusage.php: call to question_attempt->render()
- line 253 of /question/preview.php: call to question_usage_by_activity->render_question()
After this student could not continue the test and have to wait when it will close automatically (for us this time is 2 days) and after that he will be able to start new attempt.
I don't know how to resolve the problem.
Many thanks for all replies!
