I don't understand what your response means. You would like to share....
the model part of it? I can't see any difficulty in that; it's a set of
Actions, the valuestack introspects the set until it finds a value that
matches a given name (actually, an expression that can go down attribute
chains to find a value) to get values out of the model. But what does "as
I read it in a book" mean?
