Re: [Boost-users] question about boost serialization library

I'm wondering whether it may be something to do with the NVP
serilisation of *this - does the serialisation lib know how to name
*this to correctly form a NVP? What did the original XML say?

void save(std::ostream & os)
{
        assert(os.good());
        boost::archive::xml_oarchive oa(os);
        oa << BOOST_SERIALIZATION_NVP(*this);
}
