Issue 1: Application reports error when attempting to save unchanged data
Project Member Reported by alex.bes...@gmail.com, Jun 25, 2010
What steps will reproduce the problem?
1. Lookup a candidate, contest, or seat.
2. Open the edit page, but do not make any pages.
3. Click 'Save'.

What is the expected output? What do you see instead?
The application reports that the save failed, because no rows were changed in the db.  Instead, the app should either report that the save that was successful or that no data was changed.

Please use labels and text to provide additional information.
This affects do_edit_candidate.php, do_edit_contest.php, and do_edit_seat.php
