Who got Google Maps V3 and Ext JS 4 running in a window panel?
I can't get the code of @VinylFox to work. I have added ext-all.js and ext-all.css, and his Ext.ux.GMapPanel3.js. Error: Uncaught TypeError: Object #<Object> has no method 'reg'. I guess the system of registration an extension has changed but not in this extension.
