I am trying to get to use a wosrkshop activity. I am using Moodle 1.7 and firstly I had a problem with the insertion of assessments but I managed to solve it by putting the following lines
$assessment->generalcomment = "";
$assessment->teachercomment = "";
in the assess.php and locallib.php.
Now when I try to grade the workshop I get the following error
Could not insert workshop grade!
