2192: Duplicate posts when clicking [Add comment]

July 27, 2011
What version are you running?
Reviewboard 1.6 RC2

What's the URL of the page containing the problem?

What steps will reproduce the problem?
(Screenshots attached, follow along)
[0001.png] Visit your review URL (e.g. http://path.to.reviewboard/r/<number>/)
[0002.png] Click "Add comment" and type a comment
[0003.png] Click [OK] or press Ctrl+Enter
[0004.png] Double-click your newly created comment OR click the pencil icon
[0005.png] Edit your comment to something else
[0006.png] Click [OK] or press Ctrl+Enter
[0007.png] At this point, your original comment should be gone, having been replaced by your new comment.
[0008.png] Click [Publish]

What is the expected output? What do you see instead?

At this point, only your NEW comment should be posted. There should be no trace of the old comment.
[0009.png] Notice that the e-mail from reviewboard illustrates that BOTH comments were in fact posted, and in opposite order to each other. This suggests some sort of copy-on-write behavior where atomicity should have been otherwise violated...
[0010.png] Refreshing the reviewboard webpage shows the same thing. Both comments are now visible, even though we really only intended to make one.
