    The framework can access objects bypassing the setters (e.g. this is
    how Generic Persistent Class operates [1], but this is also true for
    any DataObject).

    So since I don't know how your code is written, I am making general
    assumptions going from Cayenne end. There are two suspects. First is
    that the relationship is nullified indirectly by Cayenne in response
    to a sequence of events in the application. One more level down this
    path - can you try putting a thread dump in 'writePropertyDirectly'
    overriden method and see if it shows anything.

    Second is that serialization is somehow involved, as deserialization
    accesses fields directly.

    These are the two ways to bypass the setters. Otherwise I am out of
    ideas (without looking at the code that is).
