      Hi guys,

      I've just tried to restore a course backup in master of the World of Water course found at http://school.demo.moodle.net/course/view.php?id=115
      There were also several notices on that page.

      First up the fatal error including stack trace:

      Debug info: ERROR: null value in column "extensionduedate" violates not-null constraint
      INSERT INTO mdl_assign_grades (userid,timecreated,timemodified,grader,grade,locked,mailed,assignment,extensionduedate) VALUES($1,$2,$3,$4,$5,$6,$7,$8,$9) RETURNING id
      [array (
      'userid' => 109,
      'timecreated' => 1341062516,
      'timemodified' => 1341062516,
      'grader' => 92,
      'grade' => '7.00000',
      'locked' => '0',
      'mailed' => '0',
      'assignment' => 2,
      'extensionduedate' => NULL,
      Error code: dmlwriteexception
      Stack trace:

      Next the notices without stack traces (hopefully not needed):

      Notice: Undefined property: stdClass::$teamsubmissiongroupingid in mod/assign/backup/moodle2/restore_assign_stepslib.php on line 76

      Notice: Undefined property: stdClass::$groupid in mod/assign/backup/moodle2/restore_assign_stepslib.php on line 114

      Notice: Undefined property: stdClass::$extensionduedate in mod/assign/backup/moodle2/restore_assign_stepslib.php on line 142

      My apologies if there are already issues for these, I had a quick search but didn't find anything.

      To reproduce:

      1. Log into http://school.demo.moodle.net/course/view.php?id=115 as a manager
      2. Create a backup of the course and download it (use defaults)
      3. Restore on your local site (all defaults) and follow through until you need to map roles
      4. When asked to map out the roles just leave parent as nothing (doubt this is important but just so its known what I did)
      5. Click continue and wait (can take some time)
      6. Observe above errors.
