May be it is a basic question. I am new to Geoext programming. I have developed a web application using Geoext with East - Table of content, Center- Map display and South - Grid panel

I am able to load a single WFS layer attributes by hard coding with Ext.store in south panel.

I would like to update/populate the south panel with Attribute table of actively selected layer on East panel. Each time a different layer is selected, the south grid must change accordingly with data relevant to it.

How to achieve it?
