Glassfish 2.1.1 locale filter

Question

I've a locale filter which sets the locale by the url and forwards the reply, and stopped working after update to Glassfish 2.1.1. There's something changed ?...
The filter code:
        if (relativePath.contains("/es/")) {
            log.debug(" before req:"+req.getRequestURI());
                req.getSession().setAttribute("c-locale", "es");
            filterConfig.getServletContext().getRequestDispatcher("/"+relativePath.replaceAll("/es/", "")).
                forward(request, response);
            log.debug(" after req:"+req.getRequestURI());
        } else if (relativePath.contains("/en/")) {
            origURI=req.getRequestURI();
            log.debug(" before req:"+req.getRequestURI());
            req.getSession().setAttribute("c-locale", "en");
            filterConfig.getServletContext().getRequestDispatcher("/"+relativePath.replaceAll("/en/", "")).
                forward(request, response);
} else {
             chain.doFilter(request, response);
}web.xml
<filter>
    <filter-name>localefilter</filter-name>
    <filter-class>com.foo.bar.localefilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>localefilter</filter-name>
    <url-pattern>/en/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>   
</filter-mapping>Instead of getting the forwarded page, I get:
javax.faces.FacesException: Problem in renderResponse: /en/page1.xhtml Not Found in ExternalContext as a Resource
Looks like Facelets didn't take the forward ¿? ... The same project under glassfish "Java System Application Server 9.1_02 (build b04-fcs)" process well the filter...
I didnt find any change in the documentation!!!
Any hints ?...
thank you very much!
PS: I'm using icefaces 1.8.1 + facelet, below the stack trace
java.io.FileNotFoundException: /en/page1.xhtml Not Found in ExternalContext as a Resource

I don't think so, as I said, in previous version works well, and I've just been testing on Tomcat 6, and forwards works like I expected.. I suspect that this is a bug in GF. I think it's time to move forward to another AS, I'm really exhausted about GF problems.
thank you for your reply,
