## Class RenderNotification

- java.lang.Object
- - org.apache.tapestry5.corelib.mixins.RenderNotification

-     @Events(value={"beginRender","afterRender"})
       @MixinAfter
      public class RenderNotification
      extends Object

  This mixin triggers component event notifications when the attached component enters its `BeginRender` and `AfterRender` render phases. A common use of this is to handle the "afterRender" event to generate client-side JavaScript for content just rendered via a `Block` (this is a common Ajax use case related to partial page rendering). Since AJAX requests don't trigger afterRender or beforeRender render phase events in the containing component or page, this mixin provides a way of accessing those events as component events.

  An example using the `Any` component within a zone:

       <div t:type="Zone" id="myZone">
           <t:any t:mixins="RenderNotification">
                    <!-- zone content ->
            </div>
       </div>

  The `MarkupWriter` is passed as the event context to your event handler method(s), so your corresponding component or page class might look like:

       void onBeginRenderFromMyZone(MarkupWriter writer)
       {
           writer.element("p");
           writer.write("before item render");
           writer.end();
       }

       void onAfterRenderFromMyZone(MarkupWriter writer)
       {
           writer.element("p");
           writer.write("after item render");
           writer.end();
       }

  As an alternative, see the `Trigger` component, which does something similar but as a component rather than a mixin.
