Decorating a standard component

["Jesse Alexander (KBSA 21)" <al...@credit-suisse.com>]

Hi

I need to decorate the rendering of a standard component (h:inputText).

I thought it should be possible to 
- subclass the standard-renderer
- define my renderer in the faces-config.xml in /WEB-INF

Well JSF does not complain, but my own renderer is not called...

renderer: 

import org.apache.myfaces.renderkit.html.HtmlTextRenderer;
public class InputTextHtmlRenderer extends HtmlTextRenderer {
  public void encodeBegin(FacesContext context, UIComponent component)
      throws IOException {
    // do my stuff
    super.encodeBegin(context, component);
  }
  public void encodeEnd(FacesContext context, UIComponent component) throws IOException {
    super.encodeEnd(context, component);
    // do my stuff
  }
}

faces-config.xml:
<faces-config>
	<render-kit>
      <renderer>
          <component-family>javax.faces.Input</component-family>
          <renderer-type>javax.faces.Text</renderer-type>
          <renderer-class>com.csg.jsf.components.input.InputTextRenderer</renderer-class>
      </renderer>
	</render-kit>
</faces-config>

Somebody an idea / hint?

regards
Alexander
