Extended @FacesComponent as composite interface componentType renders nothing

Question

I\'m trying to extend JSF\'s component class (let it be one of h:panelGroup) and render it via composite component:

Step 1:

@FacesCompon         


        

Answer 1

The backing component of the composite component must implement NamingContainer and the getFamily() must return javax.faces.NamingContainer. See also description of the componentType attribute in the <composite:interface> tag documentation.

@FacesComponent(value="customPanel")
public class CustomPanel extends HtmlPanelGroup implements NamingContainer {

    @Override
    public String getFamily() {
        return UINamingContainer.COMPONENT_FAMILY;
    }

}

You can also choose to extend UINamingContainer instead, so that you can omit the getFamily().
