Barney,
That's why I pass a fieldlist argument in. If "numberOfGrandchildren"
isn't in the fieldlist then I don't calculate it.
Does that not cover that case?

By front-computing all those values, you're necessarily doing a LOT of
extra work to build up data that isn't needed universally. A dataDiff
for age is simple, but what if it's numberOfGrandchildren (which is
guaranteed to require database access to answer). Using a method for
lazy loading the data can be a HUGE performance boon, as well as
moving a huge amount of entity-specific logic into the entity (rather
than in external components divorced from the entity itself).
But like you said to Peter, I think we have to agree to disagree on this. :)
cheers,
