title: Looking for a sample application with ExtJS + Grails
body: <p>Although I prefer libraries that are open source, ExtJS has really nice set of widgets that could save me tons of time. So I am leaning towards using ExtJS for the view. However, when I did the search on the web trying to find a sample application that can get me started quickly, I didn't find one. I wonder if this means ExtJS + Grails is not that popular in the Grails world, or am I missing something? </p>
