[Users] "GeoExt.grid.FeatureSelectionModel()" destroys Layout

[Matt Priour]

I'm not sure why it is breaking your layout, other than the code is erroring 
out and not completing the layout.
To use the GeoExt.grid.FeatureSelectionModel, your grid panel MUST have a 
layer property.

Looking at the code below, I don't see any "layer"  property configured in 
your grid panel.
