   The spec actually forces us the use producers for "cc" and "component but it leads to a bad performance.
   Also @Inject UIComponent doesn't make sense and wouldn't work correctly if we don't create a own "ComponentScoped"
   or something.
   We will still use ELResolvers for this - see ImplicitObjectResolver#makeResolverForFacesCDI().
