"Upload failed: OK"

[Anton Ekblad]

A lab group (https://xdat09.ce.chalmers.se/2015/lp1/cp/admin/labs/2/submissions/group53) in the concurrent programming course is having trouble uploading files after receiving a reject. Whatever they try, they are met by the message "Upload failed: OK". I logged in as one of the students, and I get the same result.

Steps to reproduce:

1. Log in as student
2. Click "add file"
3. Select file in dialog

Expected result: File uploaded and displayed in file list

Actual result: File is (seemingly) not uploaded, nor added to file list; message "upload failed: OK" is displayed in the file list, "submit" button is disabled and reads "wait for upload to finish..." See attached screenshot.

Sorry about the lack of detail in these bug reports; I only have what I got from the students.

When I made an empty submission for the group, that submission turned up as submission 1, and their actual submission 1 that was previously rejected became submission 2 - what?

Another group apparently caused the "re-submission becomes submission 1" problem described above on their own, but they were able to upload files: https://xdat09.ce.chalmers.se/2015/lp1/cp/admin/labs/2/submissions/group61

The students' description of the problem:

I have some problems with Fire. The files of an older submission, that we never submitted, showed up and we couldn't delete them. So we submitted them, but they can't be withdrawn anymore.

I'm starting to think this may be related to #86?

Yes, they were caused by the same bug. It has been fixed by 6a46dca (see commit message for details). I fixed the submissions in the database, they are in correct order now. Thank you for detailed report!
