Hello,

For a number of online courses grading isn't all that useful (it may even be a deterent).  In trying to set up an exercise that wasn't graded though we ran into a bit of a problem (in the CVS version) which I think can be cleaned up pretty easily.  We want everyone to be able to add comments for peer evaluation, but not actually grade it.

These are the settings I chose--
Grade for Participant Assessment: 0
Grade for Submission: 100
Grading Strategy: Not Graded
Handling of Multiple Submission: Use Mean
Number of Comments etc: 0
Comparison of Assessments: Fair
Use Password: No
Password: Blank
Maximum Size: 2MB
Deadline:
Number of Entries in League Table: All
Hide Names from Students: No

/mod/exercise/assessments.php?action=editelements&id=59

When I click "Save" I am directed to page on "Editing Assessment Elements"
(which I cannot get out of)
Clicking on "Save Changes" gives me the following error

"Warning: Invalid argument supplied for foreach() in
/mod/exercise/assessments.php on line 464"

This just needs a quick check to see if there are any assessments before foreach is attempted.  Either that or a @

It would be useful to have a quick note when you are on the editelements page that tells you that there are no elements to edit and gives you the option to view the exercise (or something like that).

Thanks!

Mike
