ColdFusion 8: Screencast of cfAjaxProxy, the Tag That Blurs The Line Between CF and JS
ColdFusion 8The cfAjaxProxy tag creates all the JavaScript needed so you can call functions in a cfc directly from JavaScript. This 3 minute screencast walks through a simple, yet powerful, example.
This was also the first time I played with the Derby database examples provided by CF (and found out its case sensative!). The code in the screencast is below.

Another excellent demo, Sam!
I think cfajaxproxy is really going to make it easy for folks to write their validation code once (in CFCs) and then leverage that code for both client-side validation (using cfajaxproxy) and server-side validation (to handle cases where users have JavaScript turned off).

Thanks!
I think form validation is an interesting potential for cfajaxproxy but would want to do some performance tests first. Users often expect validation to happen instantly
