At first blush, Mary Glackin's report on Sakai Dev this morning looks quite similar. I've assigned this to Louis.

So is the use experiencing the problem in both sites - as a student and also separately as a TA. . I s this the same

My guess is that the user is experiencing it in the site in which he/she is a TA. I don't know if the two reports are

Although without further information we can't be sure that this is the cause of the problem, after looking at the c
the folllowing scenario:
1) Start with an unscored student. Two graders open the gradebook for the site and go to the Assignment Details
2) Grader 1 gives the previously unscored student a score and saves changes.
3) Without refreshing the screen, Grader 2 gives the same student a score and tries to save changes.
Stephen, if your logging is set at the INFO level, could you see if there are two matching "INFO AssignmentDet

The bug I see in the code, by the way, is that we decide whether this is a new data object or not based on reading

Sorry, I don't think we have those logs any more. We don't generally keep our tomcat logs around for that long.
