setDisplayValueOnly does not work on HtmlSelectOneMenu

Hi,

I am running this simple example below trying to set the setDisplayValueOnly on HtmlSelectOneMenu to true

It does print out: “in buildComboBox !!!!menu.isDisplayValueOnly:true” but I still see the menu widget on the screen.

I am using MyFaces 1.1.6  

import org.apache.myfaces.component.html.ext.HtmlSelectOneMenu;

private static UIComponent buildComboBox(List values, String bindingValue, String idPrefix, int id, boolean immediate, String defaultElection) {

            HtmlSelectOneMenu menu = new HtmlSelectOneMenu(); // combo box

            ValueBinding binding = app.createValueBinding(bindingValue);

            menu.setValueBinding("value", binding);

            menu.setId(idPrefix + "_" + id);

             menu.setRequired(true);

            // populate the drop down list

            UISelectItems items = new UISelectItems();

            items.setValue(values); // add choices to list

            menu.getChildren().add(items);

            if(defaultElection!=null){

                  menu.setValue(defaultElection);

            }    

            menu.setDisplayValueOnly(true);

            System.out.println("in buildComboBox !!!!menu.isDisplayValueOnly:"+menu.isDisplayValueOnly());

            return menu;

      }

Any thoughts?

Thanks

Yaron
