Review draft, invalid user/group warning.
Review Request #1785 — Created Sept. 23, 2010 and submitted — Latest diff uploaded
This is addressing the issue here: http://code.google.com/p/reviewboard/issues/detail?id=1773 When creating a review draft, if a user or group doesn't exist, a message will notify the user of the error. Currently the invalid user or group would simply be removed. Message varies based on number of mistakes.
Manual testing. Tried editing everything on the draft page, seems to be working fine.
