CodeIgniter + ExtJS 2.2 ? Tutorial?

[eluser]Mirage[/eluser]
I don't have a tutorial, but I've integrating with Ext since before 2.0. I really don't see what's to integrate? ExtJs runs on the client and makes HTTP Requests. On the CI side of thing you do the same thing you'd do for regular browser requests. Except that your output is often not html, but rather JSON or XML.

Either way - CI itself has little to do with any of this...
