The differences between start-state and start-page are explained (perhaps not clearly?) in the docs. Both are valid ways of starting a pageflow depending on where you are. And the exception is very helpful: (note that pageflows that begin during the RENDER_RESPONSE phase should use <start-page> instead of <start-state>) If you think this can be more clearly in the docs, it would be great if you can provide some more/better text View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077208#...
