I found something.

In org.picketlink.identity.seam.federation.ExternalAuthenticationFilter.doFilter(), requests that are relevant to the SSO process do not go through the filter chain. As such, they don't go through javax.faces.webapp.FacesServlet which establishes the context for regular JSF calls. However, this context is still required when the redirection is executed (see my previous message) hence the exception.

if (service != null){
         try{
            new ContextualHttpServletRequest(httpRequest){
               @Override
               public void process() throws ServletException, IOException, LoginException{
                  try {
                     doFilter(httpRequest, httpResponse, service);
                  } catch (InvalidRequestException e){
                     httpResponse.setStatus(HttpServletResponse.SC_BAD_REQUEST);
                     if (log.isInfoEnabled()) {
                        log.info("Bad request received from {0} ({1})", e.getCause(), httpRequest.getRemoteHost(), e.getDescription());
                     }
                  }
               }
            }.run();
         } catch (ServletException e) {
            throw new RuntimeException(e);
         } catch (IOException e) {
            throw new RuntimeException(e);
         }
      } else {
         // Request is not related to external authentication. Pass the request on to the next filter in the chain.
         chain.doFilter(httpRequest, httpResponse);
      }

Thanks Marcel. I removed that redirection from pages.xml (the reason for it is that in my case, there is a business requirement to always send the user to the main page after the login even if he attempted to access another page).

I was merely explaining why I had that declaration in components.xml; I didn't mean to imply the original problem was still there. Thanks again for all the help.
