Hi at all,

i'm not sure if this is the right place for my question, but I suppose some 
connection to the usage of ExtVal in my project since the suggestions found in 
some tutorials do not work.

I'm using a third party component whose renderer does not meet my demands. 

a) First try was to add a custom renderer to the default renderkit in 
faces-config. Problem is: the renderer is registered at one time, but after 
this the original renderer is registered again thus overriding my renderer. The 
reason for this is unclear to me, what I can see is a lot of ExtVal processing 
and the usage of some renderer wrappers.

b) Second try was to define another default renderkit in faces-config:

  public class MyRenderkit extends RenderKitWrapper {

        private final RenderKit mojarraRenderkit;

        public HISExtendedRenderkit() {
                mojarraRenderkit = ((RenderKitFactory) 
FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY)).getRenderKit(FacesContext.getCurrentInstance(),
 "HTML_BASIC");
        }

       @Override
        public Renderer getRenderer(String family, String rendererType) {
           // return custom renderer

What I get here is an ExtVal implementation again and not the one of mojarra: 
ExtValRenderkit. And in addition the getRenderer-method of MyRenderkit is never 
called later on.

What is the correct way to replace the third party renderer with my custom 
renderer while not facing ExtVal internals and implementation classes (such as 
DefaultFactoryFinder, ExtValContext and so on).

Thanks.
