CJAX and CI - responses vs controllers - accessing CI goodness

[eluser]Ajaxboy[/eluser]
As shown in the included ci samples, you must extend the CI_Controller in the response so that all the CI core is available to you, then preferably turn on errors on to see any errors if any.

Taken from application/response/test.php

class Test extends CI_Controller {

I also recommend firebug (for firefox) or chrome debugger (for chrome) to monitor the ajax responses. Regardless of anything else, you should always get a response back, and there is where these are used.
