actually we are inconsistent in some places and i have been trying to fix
it. what we mostly do is whenever we work with a collection we clear it and
repopulate it. but we never call setobject() on the model which imho is
wrong. sometimes i have a model in between that depends on setobject()
called whenever a property is updated because it does some translation and
its a lot easier to proxy a model then it is to proxy a collection. just my
2c.

There's not always a need for setObject to be called. I haven't read
the whole thread, but in the above example, you work on a property
('cb') of the person, so all you have to do (probably) is do something
with this updated object (like saving it). You would only do setObject
when you would provide a new person, and when the getObject
implementation wouldn't take care of that.
Personally, I rarely use/ depend on setObject as working with
properties of objects is a very typical thing to do.
Hope this makes sense,
Eelco
