      Try the attached package in the latest stable Moodle environment.

      On save/suspend of the data model I receive a warning about insufficient choices for the correct_responses pattern. On debugging I found this to be a single alert() error in the code that doesn't really apply when setting the correct answer to a multi-choice question.

      However, the more concerning problem is that when the session is resumed the JavaScript outputted by Moodle is syntactically invalid and causes the whole SCORM 2004 support to fail. The affected JS is part of data model reinitialisation:

      cmi.interactions.N0 = new Object();
      cmi.interactions.N0.objectives = new Object();
      cmi.interactions.N0.objectives._children = objectives_children;
      cmi.interactions.N0.correct_responses = new Object();
      cmi.interactions.N0.correct_responses._children = correct_responses_children;
      cmi.interactions.N0.type = 'true-false';
      cmi.interactions.N0.weighting = '1';
      cmi.interactions.N0.correct_responses = new Object();
      cmi.interactions.N0.correct_responses.N0 = new Object();
      cmi.interactions.N0.correct_responses.N0.pattern = 'true';
      cmi.interactions.N0.result = 'correct';
      cmi.interactions.N0.timestamp = '2010-01-19T12:27:41';
      cmi.interactions.N0.description = 'Does lamp LP A light up?';
      cmi.interactions_N0.correct_responses._count = 1;
      cmi.interactions.N0.objectives = new Object();
      cmi.interactions.N0.objectives.N0 = new Object();
      cmi.interactions.N0.objectives.N0.id = 'urn:LJCreate:Objective-M2470001-C001-1';
      cmi.interactions.N0.id = 'urn:LJCreate:Interaction-M2470001-C001-2_1';
      cmi.interactions.N0.learner_response = 'true';
      cmi.interactions_N0.objectives._count = 1;

      The problem there is that underscores are appearing instead of object namespace dots for the ._count fields.
