    I'm trying to update some data about my objects when they are saved.
    I have several different classes of objects which are saved. My
    solution is to use DataContextDelegate's finishedMergeChanges but it
    appears never to be called. When I call DataContext's commitChanges,
    does this trigger the delegate's finishedMergeChanges? My other
    solution is to call my update method in ValidateForSave but this
    would mean I would have to manually add in this call for each class.
    (Or I could subclass CayenneDataObject but this seems inelegant to me.)
