public class AjaxFreeMarkerView
extends FreeMarkerView

Tiles view implementation that is able to handle partial rendering for Spring Javascript Ajax requests.

This implementation uses the SpringJavascriptAjaxHandler by default to determine whether the current request is an Ajax request. On an Ajax request, a "fragments" parameter will be extracted from the request in order to determine which attributes to render from the current view.
