At my institution, a Workshop activity has been setup to allow students to peer assess work. Each student is allocated three assignments to peer assess upon submitting their own assignment.

However, when students are attempting to peer assess, students see the message: "workshop_list_student_submissions: unable to get submission".

As yet, I have not been able to see if this bug has been reported or fixed – I have searched the Moodle Bug Tracker. A discussion took place at http://moodle.org/mod/forum/discuss.php?d=30234 which suggested a "hack".
