Re: Inner Activity Place Token Changes

I don't understand how your activity gets the info about the Place (in your case, the filter to apply).

If we think about the ActivityMapper as the one place that knows about both the Place and the Activity and how to bind them together, then each Activity should expose its own API and the ActivityMapper should then call it. In your case, that could be:

// in the activity

public void setFilter(String filter) { ... }

// in the mapper

if (place instanceof CustomersListActivity) {

   if (lastPlace instanceof CustomersListActivity) {

      lastActivity = createSearchActivity(((CustomersListActivity) place).getFilter());

   } else {

      ((CustomersListActivity) lastActivity).setFilter(((CustomersListActivity) place).getFilter());

   }

} else {

   // handle other places

}

// keep track of the last seen place

lastPlace = place;

return lastActivity;
