Why not make your pages consult some kind of service that builds the

Hi Pieter,
Ok, what I do in situations like this is to create a new transient,

point by calling factory.store(object). Not sure about hibernate.

nah. the problem with storing navigation in session is that it will
get out of sync when the user uses the backbutton. a proper way to
