how to avoid "instanceof" checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?

GWT MVP ActivityMappers have lots of "instanceof" checks [*] for mapping a given Place to the corresponding Activity (or to a more specific AcitivtityMapper). I was wondering if there is a way to avoid using "instanceof" checks, and instead use an elegant Object Oriented approach. I looked into

The PlaceHistoryMapper implementation generated by GWT.create() enforces these prefix+token pairs (it extends AbstractPlaceHistoryMapper), but PlaceHistoryHandler does not, and you can very well implement the PlaceHistoryMapper interface by yourself, using the "pattern" you like. In this case t
