Re: Activity / Place + History.back()

So I solved my problem. We'd created a convience method that called
EventBus.fireEvent(new PlaceChangeEvent(Place)) instead of using the
PlaceController.goTo(Place). This was causing issues because even
though it felt the same it wasn't updating the "where" Place property
of the PlaceController so when History.back() was called it was
checking against a stale "where" object.
