We researched the Google AJAX toolkit and found that it was very low level and required a lot of hard wiring in javascript to get it to work. We're starting to adopt the DOJO toolkit which is more of a 4GL comparied to Google's and even Yahoo's.
We're just now starting to integrate with ofBiz and eventually will attempt to pull it in. For more info on DOJO, checkout http://dojotoolkit.org/. John
