Tapestry tutorial advice

[Andrus Adamchik]

I am reworking Cayenne tutorials for 1.2 final release. Since I  
haven't used Tapestry for almost a year, and totally missed on 4.0, I  
wanted to get some feedback from Cayenne/Tapestry users. What are the  
good ways to bind DataContext to a session?

Current example puts it in the visit. I would personally use a  
regular web app setup with Cayenne filter (making Tapestry app just  
another web app case as far as Cayenne is concerned). I wonder what  
others are doing in this respect? Any HiveMind magic?
