If you want to updgrade from Coldfusion 8 to Coldfusion 9 on your server then think twice before doing this. If you are working on big project where you have widly used coldfusion ajax component and custumize and play with ExtJs function for enhance your ajax functionality then this will be nightmare for you to migrating to Coldfusion 9. Main reason behind this is ColdFusion 8 is using ExtJs 1.X as ajax/javascript function and in Coldfusion 9 Adobe has used ExtJs 3.0. Below is quotes from ExtJs site for migration from Ext 1 to 2.
"Unfortunately, because of the architectural changes in the new version of Ext, it was not possible to maintain full backwards compatibility. While the Overview will help get you oriented with the new code base, this guide will provide the practical steps needed to migrate your code as painlessly as possible."Means you may need to look at your all pages where you have applied enhance ajax functionality and this what I am doing right now.I am playing with cfgrid, cflayout and cfwindow which I have widly used in our system.
I will keep posting about migrating from CF 8 to CF 9 for different ajax component.

We already shifted to cf9 and working fine for us. Yes issue is not related to coldfusion but it related to extjs version. So it will only affect you if you are have customize some script.
You visit my other blog regarding cfgird, cflayout and cfwindow.
And feel free for any related question if you have. I please to answer you.
