    You can use custom
    org.objectstyle.cayenne.property.ClassDescriptorFactory to customize
    how the objects are built. The factory is set on the DataDomain's
    EntityResolver. Specifically custom factory will need to tweak how
    ToManyListProperty operates to return a subclass of NSArray that
    implements ValueHolder interface.

    Also I believe you will need to patch the faulting mechanism, that
    currently uses static fault singletons in a few places (search for
    'Fault.getToManyFault()'), and replace it with ClassDescriptor based
    approach.

    We won't be able to apply them now, but RC also means that the new
    release cycle will soon start. Stay tuned.

    I like Click. Don't know how representative this is of a "former WO
    user" :-)
