Zhen,

I exported the result as xml. Let me know if you prefer other formats, html/csv/sql/txt...

Kelly:

Can you find the assignment id and query for all its submission objects?

select * from assignment_submission where context='<assignment_id>'

Please send me the query result.

Thanks,

- Zhen

p.s. Here is how you can get the assignment id:

1. view frame source for the following screen and locate the link for assignment title "Paper #1"

2. the link should be formatted as "http://<server_name>/portal/tool/<tool_id>?assignmentId=/assignment/a/<site_id>/<assignment_id>&amp;panel=Main&amp;sakai_action=doView_assignment<view-source:http://localhost:8080/portal/tool/mercury-610?assignmentId=/assignment/a/mercury/928b9dfb-b036-402e-a6c3-e495370c689c&panel=Main&sakai_action=doView_assignment>">, just take the assignment_id param out.

Hi Sakai developers,
One of the instructors was trying to batch-upload "feedback as attachment" for all students and encountered an error(which was not captured). After that, she can no longer access the submitted assignments because the following error shows up in place of the number of submissions(see attached screenshot). Anyone has any idea what this is about? We are running sakai2.7.x.
Thanks!
