Peter:
It is working now.
I have some recommendations on your Find a Address widget based on experience with a similar tool in one of my organization's GIS parcel based web app.
Based on how your geocode results are displayed, it looks like your composite geocode service is performing a road centerline geocode search before a parcel geocode search. I would think the parcel geocode search is more important and I would perform that search first.
I entered a legitimate address without city or zip and it returned no results. I would think you would want to get search results even if you do not have the zip as someone searching an address might not have that information.
