You can get the layer name out of the attr object that is passed too. In my
case I have a GeoExt.data.LayerStore that contains the layers so I can find out
the layer name by doing:
var layer = store.getById(attr.layer.id).get('layer');
var layer_name = layer.params.LAYERS;
There might be a better way but it works for me.
