[Building Sakai] weird bug in assignments: it's showing the

Chuck: 

We are currently running 2.7.1 with extra patches. 

However, I cannot repeat the problem by following the step below. Could you
provide more details here? 

Thanks,

now happening at at least 3 places. Any commonality in sakai versions? We
hadn't seen it under 2.7.0, but are seeing it in 2.7.1.  Yes, they are
inline text, not attachments.  What's happening is the following: 
instructor hits "next" new screen comes up with text from old screen in FCK
instructor does next or previous an automatic save occurs. The contents of
FCK are saved as feedback, i.e. Sakai thinks it's a version of the
student's assignment with instructor comments  The database shows the
correct submission, but the wrong one as feedback. If you go back to the
assignment in the UI, you'll see the wrong data, because when feedback
exists, the UI will show it rather than the original submission.  We think
other data such as
grade may also be duplicated, but we can't be sure yet. 
I don't see how having another window open would have any effect. The
instructor is going from one student to another in the same window. I
understand that doing that isn't safe, but it wold require a very strange
and unlikely pattern of actions in the two windows to cause this effect. 
It's happened enough that I consider it a crisis.

    Hello,   We, University of Florid, are having the exact same problem,
which happened yesterday. That's for inline assignments, not attachments as
well as unlimited submissions. The instructor claimed that he knew there
was a problem as soon as he opened it, because the student names did not
match up. He even did not try to give any inline comments or scores due to
this error. But he admitted that there could have been another browser
open.   My question is that which database table stores student's view
content and which one stores
instructor's view content. When I logged in as
Student A, Student A's submission contains "content A", and Student B's
submission contains "content B", which are correct. However, when I logged
in as instructor, then Student A had "content A", which is right, but
Student B also has "content A", which is wrong. Since student's view
contents are correct for both case, but instructor's view contents are
different, I would like to start to investigate the db first. If you know
any related java classes, please let us know that too. Thank you in
advance.   Sanghyun
