CachingActivityMapper seems not working

Question

I use MVP pattern for GWT application. I have a filter view and search results view. If the search criteria is modified, search results are getting updated.

But, the selected criteria lost when I refresh the browser. So I want to retain the search criteria and tried using CachingActivityMapper in my onModuleLoad()

 CachingActivityMapper cached = new CachingActivityMapper(new AppActivityMapper(clientFactory));
 FilteredActivityMapper.Filter filter = new FilteredActivityMapper.Filter() {
      @Override
      public Place filter(Place place) {
        return place;
      }
    };

 final ActivityManager activityManager = new ActivityManager(activityMapper,
            eventBus);      
 activityManager.setDisplay(filterDisplayView);

But I dont see any difference.

Kindly tell what went wrong in my code.

Thanks.

There's nothing in the docs for CachingActivityMapper to suggest that it is able to store anything between page reloads. It isn't your code that's wrong here but the assumption that a CachingActivityMapper is reload-resilient - it is not. Reloading the page means rebooting your app and loosing all its runtime state, including anything a CachingActivityMapper may have cached.

So, is there a way to add my filters into the URL? So that I can get the runtime filters when the page is refreshed – Sree Jan 07 '13 at 21:40

Look into this for implementing Local Storage. This could solve your problem.
