>             Project: JBoss Seam
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: 2.0.0.GA
>            Reporter: Werner Kolov
>         Assigned To: Norman Richards
>             Fix For: 2.0.1.GA
> Try to add following 3 entries to your pages.xml
>   <page view-id="/restricted.xhtml" login-required="true">
>     <restrict>#{s:hasRole('doesNotExist')}</restrict>
>   </page>
>   <exception class="org.jboss.seam.security.AuthorizationException">
>       <redirect view-id="/home.xhtml">
>           <message>You don't have permission to do this</message>
>       </redirect>
>   </exception>
>   <exception class="org.jboss.seam.TransactionException">
>     <end-conversation/>
>     <redirect view-id="/exceptions.xhtml">
>       <message>#{messages.seam_specific_exception}</message>
>     </redirect>
>   </exception>
> You will never be redirected to /home.xhtml after an AuthorizationException, because the exception class org.jboss.seam.TransactionException does not exist (any more) in Seam 2.0. Sure, this is a configuration error, but unfortunately you are not prompted about it during the parsing of pages.xml. The parser simply drops ALL exception handlers, if one of them is wrong, so the complete custom exception handling and all <restrict> tags don't work. This error can easily happen, if you migrate from one Seam version (1.2.1) to another (2.0.0) and some exception classes change.
