But then, if you're using Flex Builder, you lose all the autocomplete

Flex Builder keys off the ActionScript value objects, which
They __type__ hack is only on the server side, to allow you to pass
structures to Flex and fool it into thinking it is a CFC, since CFC creation
is too slow when dealing with larger numbers of CFCs. On the Flex side they
convert to actual ActionScript classes so you still retain all the code

Lori,
The reason that some people discourage the use of a query object as a return
type is due to the fact that it binds whatever uses that query object
directly to the database (more specifically, to the columns in the
database).
The use of setter/getter beans should be familiar to your boss;

I'm definitely not the authority on ColdFusion and OO, however I have
asked lots and lots of questions. The answer is almost always, 'it
depends.' I return query objects all of the time. Sometimes I'll
return a struct with a couple of variables and the query object inside.
Do what makes sense
One of the things that the other posters (particularly Matt) were getting at
is that many times when you return a query object with a number of records,
you're not looking to manipulate any of the records (yet).
You're often listing records from the database so that one can be chosen for
9 matches
