Re: sendRedirect throws illegalstateexception

[Andrew Robinson]

Put breakpoints in the HttpServletResponse code or the sub class if someone has wrapped the "real one" or build your own wrapper that uses "System.out.println" in the addHeader/setHeader methods.

(there is no easy way besides debugging).

The other alternative is to remove all of your phase listeners and servlet filters and if that fixes the problem, add them back 1 by 1 until the problem occurs again.

we just use one phaselistener defined in faces-config.xml

                        base.presentation.common.ShowPhaseListener

        </lifecycle>
and one extension filter(i think it won't effect the response,right?)

   <filter>
        <filter-name>extensionsFilter</filter-name>

<filter-class> org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class>
</filter>
How can i know whether there is something wrote to the header before
redirection?
Thank you.
