Here, Jay walks you through how Ext JS Data Stores and GridPanels work. First by a slide show, illustrating how the utility classes are used, then an actual live code walk through.

Jonathan Julian is going to share and elaborate on five areas to improve your Ext JS applications, which range from defining your own components to properly overriding the framework.

Shea Frederick will be guiding us through advanced JavaScript debugging techniques, demonstrating some of the best tricks for the latest and greatest JavaScript development tools.

Jay will explore the benefits of using base classes to improve and standardize application infrastructure.
He will walk through a real time example writing a base class and two implementation classes.

This version has been checked into svn.

A few changes / enhancements to note:

1. each filter may be configured via the column model (less repetition of code)
2. the filter query format is configurable to use json format
3. filters will automatically reconfigure if the grid is reconfigured
4. filters clean up after themselves (there was no cleanup in previous version)
5. filter classes utilize form fields, so you can configure the fields to use validation for example
6. filters may be dynamically disabled from user manipulation (still experimental)
7. icons are modifiable just like any other menu and css (even with IE6 — see attachment)
8. complete documentation, click here to see it.
