Enjoying working with cakePHP and Ext YUI for an interesting web application

From the last July 2008, I was assigned to an interesting and complex web application project (named - TMT). Its an open source web projects.
As server side framework, I am using cakePHP and for the front side view yahoo javascript tools (Ext. YUI).
cakePHP: yes, makes easier all the area of PHP common coding.
Ext (YUI): Look ups are really beautiful. But, working is sort of complex for first time. Now I am really enjoying and solving all the problems and complexities of mine and my colleagues.
