Subject Re: [OFFTOPIC] What I wish that JSF 2.0 would be like...
Date Wed, 27 Sep 2006 00:42:14 GMT

One more:

    * New listener for FacesServlet startup/shutdown. Some JSF 
extensions may need to do some initial configuration on startup and 
shutdown but these extensions can't add a ServletContextListener to 
web.xml. ATM you can get similar behaviour by using a PhaseListener and 
deregistering it after it is first run, but that is just a workaround
