code: private void configureResolverForJSP(JspApplicationContext appCtx, RuntimeConfig runtimeConfig)
      {
          FacesCompositeELResolver facesCompositeELResolver = new FacesCompositeELResolver(Scope.JSP);
          appCtx.addELResolver(facesCompositeELResolver);
          PhaseListener resolverForJSPInitializer = new ResolverForJSPInitializer(
                  createResolverBuilderForJSP(runtimeConfig), facesCompositeELResolver);
  
          LifecycleFactory factory = (LifecycleFactory) FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
          for (Iterator<String> iter = factory.getLifecycleIds(); iter.hasNext();)
          {
              factory.getLifecycle(iter.next()).addPhaseListener(resolverForJSPInitializer);
          }
      }
docs: Register a phase listener to every lifecycle. This listener will lazy fill the el resolver for jsp as soon as the
  first lifecycle is executed. This is necessarry to allow a faces application further setup after MyFaces has been
  initialized. When the first request is processed no further configuation of the el resolvers is allowed.
