Ah, I see it now - I think I had been working too long
on a Sunday! Of course my view class does mention the
adapter Interface, and becuase there is no easy way of
doing this in the ZPT, that's why the view class is
needed. Fair enough.

I'm interested in the theory behind whether to provide
a method or a property from an adapter. I had
initially used a method, because I was following the
examples from the books (which are on the ISized
adapter, which provides two methods). Then I noticed
something along the lines of foo=property(getFoo) in
Stephan's book, which seemed to turn the getFoo method
into a foo property. Why is one better than the other?
Stephan seems to use it particularly when he has
getters and setters defined - in the case of my
ratings I think they will be calculated rather than
set, so would this lessen the relevance of the
providing a property rather than a method?
