Class RenderNotification

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

@Events({"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.
