So what I'd do is push the cache down to context object; this might be as simple as assigning the attributes you use to something on the context, or perhaps just make repeatedly accessing the source data cheap (by cachedproperty). > I'll followup on your other suggestions, and also read the link sent by > mwhudson - the discussion pre-dates my join date by a mere 5 days :-) > > Thanks for the input.
