Problem:
When trying to do any Ext based operations that involve AJAX loading of web pages or data, the operartions fail due to a bug in ext-yui-adaptor.js. This is a serious issue as it prevents the use of any underlying Ext library functions that use "lazy loading" or "AJAX derived data". The example provided is of an Ext TreePanel with recursively loaded nodes as the user drills down
Method:
\\blrfs04.macromedia.com\builds\coldfusion\bugs\82700
The followinf CFM page will create a CFWINDOW inside which is an Ext TreePanel whose data is loaded dynamically from the CFC listed below. It *should* recursively load new nodes as the user drills down through the levels

This may be linked to bug 82501, but un;like that bug, this one has no possible workaround with out a fix for /CFIDE/scripts/ajax/ext/adapter/yui/ext-yui-adapter.js
This works with a copy of the ExtJS library sourced direct from ExtJS.com
