This is actually a Catalyst question, but since Byron brought it up here 
I figured it's OK to ask it here.  I have an example of AJAX and 
Catalyst that I can't get working. (AJAX is awesome, by the way) 

http://www.dev411.com/wiki/AJAX_Select_Chaining_with_Catalyst

The example is exactly what I need, manipulating a select box after the 
page has loaded. It uses HTML::Prototype and 
Catalyst::Plugin::Prototype. Everything seems to be working except the 
select field is not dynamically populated. It appears to be a problem 
with the following line:

<head>
[% c.prototype.define_javascript_functions %]
</head>

This doesn't seem to do anything. I think it is supposed to load a set 
of functions into the header, but when I check the in-browser source 
code, nothing is there. I have installed HTML::Prototype and 
Catalyst::Plugin::Prototype on my computer. Is there something I need to 
add to my code to get it to recognize those plugins?
