public class MyPage extends WebPage {
  public MyPage() {
    WebMarkupContainer c=new WebMarkupContainer();
    c.add(new AbstractBehavior() {
      public void renderHead(IHeaderResponse response) {
        response.renderJavascriptReference(new PackageResourceReference(YuiLib.class,
          "yahoo-dom-event/yahoo-dom-event.js"));
      }
    });
    add(c);
  }
}

RequestCycle

RequestCycle has changed in 1.5-M1 and WebRequestCycle has been removed.

When we want to override RequestCycle's methods and write our logic codes we can not do it like 1.4.x.

eg.

public MyRequestCycle extends WebRequestCycle {
    @Override
    public void onBeginRequest() {
      //...
    }
    
    @Override
    public void onEndRequest() {
        //...
    }
    
   @Override         
    public Page onRuntimeException(Page page, RuntimeException e) {
        // ...
    }
}

In this case we'll need to extend RequestCycle and Override　org.apache.wicket.Application.createRequestCycle(Request, Response) to return our class.

The current entry point is　org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach().
For now we'll have to wrap this method with try/finally to simulate onBefore/onEnd.

Exception handles not like 1.4.x too we should create a new ExceptionMapper class to handle that.
