Hi Guys ... I am still facing the same problem...

Earlier with Seam 1.2 in the SeamApplication12.java the constructor used to register the methods for various usages.

         getELResolverMethod = application.getClass().getMethod("getELResolver");
         addELResolverMethod = application.getClass().getMethod("addELResolver", ELResolver.class);
         getExpressionFactoryMethod = application.getClass().getMethod("getExpressionFactory");
         evaluateExpressionMethod = application.getClass().getMethod("evaluateExpressionGet", FacesContext.class, String.class, Class.class);
         getResourceBundleMethod = application.getClass().getMethod("getResourceBundle", FacesContext.class, String.class);
         createComponentMethod = application.getClass().getMethod("createComponent", ValueExpression.class, FacesContext.class, String.class);
         getELContextListenersMethod = application.getClass().getMethod("getELContextListeners");
         addELContextListenerMethod = application.getClass().getMethod("addELContextListener", ELContextListener.class);
         removeELContextListenerMethod = application.getClass().getMethod("removeELContextListener", ELContextListener.class);

Now that code is no more there. Because of that what is happening is when i call

facesContext.getApplication.getExpressionFactory()

it doesn't go to my overridden class which is extending form   javax.faces.application.Application , but goes to SeamApplication.java instead. I am really not able to find out a way to register my method for that.

i will really appreciate any kind of help

Thanks in advance
