    I just got bit by a nasty (and rather stupid) bug today. I was pulling
    a toMany relationship, iterating it, and transforming it into another
    object. I decided to get clever and use a BeanUtils Transformer to
    clean up the code a bit and ended up transforming the list that
    actually belonged to Cayenne (in other words, replacing *DataObjects
    with non-DataObjects).

    Obviously the easy answer is that I shouldn't be careless, but I'm led
    to wonder if it wouldn't be handy for the super classes to include a
    Collections.unmodifiableList() wrapper around the ToManyList?

    I toyed with it quickly and it seems to work fine. Is there ever a
    benefit to having the reference to the DataObject's ToManyList?
