Oh, well I sort of get it. I mean I can put the attributes in using regular HTML, but I'm still not quite sure about using a GridPanel with the FeatureStore.

The demo shows setting up both the FeatureStore and GridPanel with attributes 'name' and 'elevation'. So I can get that to work if I choose two attributes from one of my layers. But what if I wanted to use the same piece of code to display the attributes for whatever feature type is being clicked? Is that possible perhaps by using a describeFeatureType request, or would I have to hard-code the attributes that I want to be displayed?

Thanks for your help Eric.
