Use one of the "on load" tools and run an action per page. In that action redirect if your bean is not initialized.
APIs: onload (onload.xml): http://jsf-comp.sf.net Seam (pages.xml): http://www.jboss.com/products/seam Shale Dialog controller (forget the URL) Each one will allow you to tie an action method to a view ID. Then from the result of your action, issue a navigation redirect -Andrew On 7/10/06, Mike Duffy <[EMAIL PROTECTED]> wrote:
