I have the following entry in my pages.xml of my Seam application

<exception class="org.jboss.seam.security.NotLoggedInException" log = "false">
        <redirect view-id="/login.xhtml" >
            <message severity="warn"> Please log in first</message>
        </redirect>
 </exception>

How ever when i NotLoggedInException occurs i still get an entry in the log file.
I am using Seam 2.1.1 GA

Please help me to identify why its not working as expected.
