Hi,
I've got the same problem:

I checked the DB:
SELECT DISTINCT event
FROM mdl_question_states
LIMIT 0 , 30
Results are : 0, 6, 3, 2
Your propose workaround:
I changed the code to:
public function get_question_status($questionid) {
$state = $this->states[$questionid];
switch ($state->event) {
case QUESTION_EVENTOPEN:
return 'open';
case QUESTION_EVENTSAVE:
case QUESTION_EVENTGRADE:
case QUESTION_EVENTSUBMIT:
return 'answered';
case QUESTION_EVENTCLOSEANDGRADE:
case QUESTION_EVENTCLOSE:
case QUESTION_EVENTMANUALGRADE:
$options = $this->get_render_options($questionid);
if ($options->scores && $this->questions[$questionid]->maxgrade > 0) {
return question_get_feedback_class($state->last_graded->raw_grade /
$this->questions[$questionid]->maxgrade);
} else {
return 'closed';
}
default:
return 'unknown';// WORKAROUND nav Mustafa probleem MN 30-06-2011
$a = new stdClass;
$a->event = $state->event;
$a->questionid = $questionid;
$a->attemptid = $this->attempt->id;
throw new moodle_quiz_exception($this, 'errorunexpectedevent', $a);
}
}
I flushed the buffers, logged in through another account, but the problem still is there!
