    No effect, captain.
    I replaced
        Util.getCommonContext().objectFromDataRow(SpisUtil.class, dr, false);
    with
        Util.getNewContext().objectFromDataRow(SpisUtil.class, dr, false)
    where getNewContext() does
        return Configuration.getSharedConfiguration().getDomain().createDataContext();

    I understand I wouldn't want to create a new DataContext for *every*
    DataObject, but I had hoped it would be proof of concept.

    Any other ideas, comments, hints as to why the above approach didn't work?

    Cheers,
    t.n.a.
