How to migrate onAfterRender/onBeforeRender from wicket 1.2.6 to 1.3

[rtow]

In wicket 1.2.6, I have the following and  render fine.

        private static class RequiredLabel extends Label
        {
                private static final long serialVersionUID = 1L;
                
                private boolean required;
                
                public RequiredLabel(String id, FormComponent fc)
                {
                        super(id, fc);
                        this.required = fc.isRequired();
                }

                @Override 
                protected void onBeforeRender()
                {
                        super.onBeforeRender();
                        if (this.required) 
                                getResponse().write("*");
                }
        }

After migrated to wicket 1.3 beta, I overrided the method as following:

                @Override 
                protected void onBeforeRender()
                {
                        if (this.required) 
                                getResponse().write("*");
                        super.onBeforeRender();
                }

The red * still render, but at the very top of the page.  A similar problem
for onAfterRender() is that also render, but at the very bottom of the page.

Thanks for your help!
