I am wondering how a page flow gets started exactly.

For the numberGuess example, is the following sequence of events corect

1. The following request is made:
http://localhost:8080/seam-numberguess/numberGuess.seam

2. The Seam interceptor gets the request. It looks for a 'numberGuess.xxx' view artifact and upon finding numberGuess.jsp renders that page

3. During the course of rendering that page, the numberGuess java bean component gets instantiated and that in turn causes the 'numberGuess' page flow to be launched.

If this sequence is correct then it is the numberGuess.jsp that gets the ball rolling instead of the numberGuess page flow.
Then what is the role of the start-page element in the page flow?
