Ajax 101 tutorial updated for Zend Framework v1.5

I’ve updated the Ajax 101 tutorial for version 1.5 of Zend Framework. At some point after I originally wrote it, the Zend Framework team removed a loophole that I and apparently many others mistakenly relied on, relating to resolution of action names. In the original version of this tutorial, I had the javascript making an Ajax call to ‘index/getData’, which was resolving to the getDataAction method in the index controller. However, as of version 1.5 of the framework, the case is not getting preserved, so that my ‘getData‘ was getting converted to lowercase ‘getdata‘, resulting in the error that Ernesto commented about way back in February:

Fatal error: Uncaught exception ‘Zend_Controller_Action_Exception’ with message ‘IndexController::getdataAction() does not exist and was not trapped in __call()’

Basically, what needs to happen is that there needs to be a word separator in the action name in the javascript so that the framework really knows how to camelcase it, such as ‘index/get-data’. I have edited the blog post and the zipped code to correct this. For an in-depth discussion of this issue, and the team’s reasoning for blocking the loophole, see the manual here: http://framework.zend.com/manual/en/zend.controller.migration.html

Sorry for any problems people have been seeing!
