Title: Unable to use a filter with redirection for single sign on

Hi

I am using MyFaces 1.0.9 and have configured an authentication filter in Tomcat 5.0.28 which does a redirect to a single sign on system.

I nevertheless receive the following error:

javax.servlet.ServletException: Unable to use forwarding (forward) after the response has been sent at javax.faces.webapp.FacesServlet.service(FacesServlet.java:125) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:237) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157) at eu.cec.trade.sigl2.filters.GacaAuthenticationFilter.doFilter(GacaAuthenticationFilter.java:58)

This does not happen if I use a jsp page in the request. When I use a jsf page and activate thus the jsf servlet, I receive the previous error.

Has anybody an idea of the problem ?
