I am enjoying using the Ext JS 2.0 library and at the same time finding it very frustrating due to a lack of well documented examples. The library is a very comprehensive object oriented Javascript library that is aimed at building data rich web applications.
To help others (especially Coldfusion programmers like me) I have started an Ext & Coldfusion wiki page on the Ext site that will, I hope, become a central place for CF programmers to leave tips about how to integrate CF and Ext.
The wiki is at http://extjs.com/learn/Manual:Resources:ColdFusion
