I just finished converting the Domain class and its respective files to use the new boolean values (along with cleaning up some method names and adding getters and setters).
Along the way I noticed some new opportunities for reusing code (especially getters and setters) and how nearly every SQL call is unchecked for error conditions! Eek. But at this point there is really very little I can do about the situation because testing the error conditions would be brutally hard without a good testing system. So this will have to wait until I can stabilize the whole system and feel comfortable with the API so I can start writing unit tests.
On that topic I should create a maintain DB that is designed for unit tests.
