In that scenario, what I would do is something like:
addresses = createObject("component","AddressIBO").init();
addresses.loadQuery(query);
user.set('addresses',addresses);
You've created an address object that now can be a property of the user
object ("composition" in OO speak)
Now you can do this:
a = user.get('addresses');
While (a.hasNext()) {
doSomethingToA(a);
}
BTW, I created a hasNext() method which is similar to isLast() but
checks whether iterator is GT than numRecords. It made more sense in
while loops.
I'm also planning on adding "add" and "remove" methods, but I haven't
needed them (yet) but now I'm off-topic ;-)

Subject: Re: [CFCDEV] ORM: Generic Child Array in Parent Bean
Interesting...
Peter replied with a similar answer:
"For child objects, you'd create another IBO, loadquery into that and
then if you had a child called Addresses, you'd User.set("Addresses",
Addresses) to load the sub object."
What meant by "create another IBO?"
I think I am way off with the following scenario, so please let me know
what I am doing wrong:
I have two objects: User and Address which have UserService and
AddressService. User extends IBO and Address extends IBO. I use
loadStruct() to populate my User object. Now I need to do a filtered
query and get all addresses with a userid of the User object. To do
that, I use AddressService to get a query of filtered addresses and then
pass the query to the loadQuery() method of the User object.
That does not sound to me like what Peter is saying to do.
