    Do you have both y and x in the same dc?
    Probably not. By default, y.setToMyClass(x) will try to convert x to y's
    dc if they are not the same.
    Since x is only a temporary object until it's committed, it probably won't
    survive the conversion.

    Try using:

    x = y.getDataContext().createAndRegisterNewObject(MyClass.class);
