All Implemented Interfaces:

BeanNameAware, InitializingBean, ApplicationContextAware, ServletContextAware, View

Direct Known Subclasses:

FlowAjaxDynamicTilesView

public class AjaxDynamicTilesView
extends org.springframework.js.ajax.tiles2.AjaxTilesView

If the request isn't an AJAX request, DynamicTilesView will handle the request. Otherwise it is expected that an AJAX view render will be next in the chain and can handle the request.

Note: Most code is copied from AjaxTilesView (giving author credit to original author). If the method flattenedAttributeMap also processed temporary Tiles context attributes, no changes to this class only renderMergedOutputModel would need to be overridden.
