If the session timeout value expires (default: 30 min.) the user should
be redirected to the login page. This worked until some time in the past
but now (using myfaces 1.0.8, Tomcat 5.0.30) we notice the following:
We have a code fragment which checks for a session attribute "loginname"
and if this check results in "null" (because the session has expired or
the user has not yet successfully logged in) we want to redirect him
using "jsp:forward":
<%
String _loginname = (String)session.getAttribute("loginname");
if (_loginname == null)
{
%>
<jsp:forward page="/faces/jsp/login.jsp" />
<%}%>
The check itself works but the attempt to redirect results in a:
java.lang.IllegalStateException: Error: Attempt to clear a buffer \
that's already been flushed
Any hints?
