Hi Folks,

Just come across a student submission with 'Submission status: Submitted for grading. the number of file(s) : 0 file(s)'. We are using 2.4.5 which I know is only supported for security fixes but I also reproduced on the latest stable 2.6 on demo.moodle.net.

Original reported here MDL-35963, closed and fixed.

I have managed to reproduce doing the following:

1. Upload a file
2. Save changes
3. Edit my submission
4. Delete
5. Save changes, receive 'Nothing was submitted' message
6. Press Back button on browser
7. Press Back button on browser AGAIN
8. End up on original submission page with file looking like it is ready to submit
9. Click Submit assignment button
10. Confirm submission
11. Receive submission status screen, everything looks OK from student view
12. View/grade all submissions as teacher/Admin
13. No file visible
14. Check logs - 'Submission status: Submitted for grading. the number of file(s) : 0 file(s)'

Still seems possible that a student is now marked as having submitted a file without actually having submitted a file! Tested with Chrome, Firefox and IE10.
