YUI-Ext tutorial for List, create, update, delete

Today I posted the following tutorial in YUI-EXT, please see the link:

Using Ext grid + form + dialog to achieve paging list, create, edit, delete function

This tutorial mainly focus on using EXT grid/form/dialog functions to achieve general paging action (list, create, update, delete). It provides a different pattern to build page instead of J2EE MVC pattern.
