Subject Re: What's the easiest way to implement two dependent select lists ?
Date Sun, 07 Dec 2008 03:35:31 GMT

I'm a Tapestry novice, but you may want to have a look at 
http://code.google.com/p/tapestry5-components/ t5components .  It allows you
to add a mixin to components to respond to an OnChange event with AJAX (see: 
http://87.193.218.134:8080/t5c-demo/oneventpage this  and 
http://87.193.218.134:8080/t5components/t5c-commons/ref/org/apache/tapestry/commons/mixins/OnEvent.html
this  for details).  You could then change the data model for the other
select component with a tiny bit of JavaScript in the onCompleteCallback
function.  

I'm curious how a Tapestry expert would handle it.
