Thank you for the quick response.

Here is my custom code

package ca.whitewaterweb.renderkit;


//
// Imports
//
import java.util.Map;

import javax.faces.component.UIComponent;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;

import org.ajax4jsf.renderkit.HeaderResourcesRendererBase;

import ca.whitewaterweb.component.UIEventCalendar;

public abstract class EventCalendarRenderer extends HeaderResourcesRendererBase {

 //This is my custom code
 public static final String CURRENT_MONTH_VALUE = "monthValue";
 public static final String CURRENT_YEAR_VALUE = "yearValue";


 @Override
 public void decode(FacesContext context, UIComponent component) {
 // TODO Auto-generated method stub
 super.decode(context, component);

 //custom code example
 ExternalContext ext = context.getExternalContext();

 Map<String,String> requestParms = ext.getRequestParameterMap();

 UIEventCalendar cal = (UIEventCalendar) component;
 String clientId = cal.getClientId(context);
 String currentMonth = (String) requestParms.get(clientId + CURRENT_MONTH_VALUE);
 String currentYear = (String) requestParms.get(clientId + CURRENT_YEAR_VALUE);

 cal.setCurrentMonth(currentMonth + currentYear);

 }


}

}

The generated renderer does not extend the base renderer that I created according to the documentation.

What is happening?

Thanks for looking into this
