If you have a MapPanel that is bound to a map, when you call map.removeLayer or layer.destroy, the corresponding layer record will be removed from the MapPanel's layer store. In addition, if you have a MapPanel that is bound to a map and you call MapPanel.layers.remove, the layer corresponding record will be removed from the bound map. In both of these cases, if you have used a LayerContainer that is configured with the MapPanel's layer store (as the LayerContainer's layerStore config property), the corresponding node will be removed from a tree when the layer is removed. The same happens for adding layers. This is how the LayerContainer example works: http://dev.geoext.org/trunk/geoext/examples/layercontainer.html In these cases, I think it is easiest to think of the layer store referenced by the MapPanel as the primary store. The the map is a view of the records in this store. The tree (in this case) can also be treated as a view. A grid could be another view. To keep things simple, don't call methods on the views.
