[Boost-users] Serialization: problems when splitting serialize into load / save

Hello out there !
I have an urgent problem concerning boost::serialize.
I have split the serialize operation into save / load as described
in the tutorial:
===================================================
    template<class Archive>
            void save( Archive &ar, unsigned int version) {
                m_offlineMode = true;
                // we cannot load more when offline --> always cachedAll
                bool oldCachedAll = m_CachedAll;
                m_CachedAll   = true;
                ar & m_CachedAll;
                ar & m_offlineMode;
                // do not serialize the lock -- use the default constructor.
                // we assume that no iterators that lock the cache do exist
when serializing.
                // ar & m_Lock;
                ar & m_LookupId;
                ar & m_LookupName;
                ar & m_SequenceNumber;
                //reset old state for the case we want to continue working
                m_CachedAll = oldCachedAll;
                m_offlineMode = false;
            }

            template<class Archive>
            void load( Archive &ar, unsigned int version) {

                ar & m_CachedAll;
                ar & m_offlineMode;
                // do not serialize the lock -- use the default constructor.
                // we assume that no iterators that lock the cache do exist
when serializing.
                // ar & m_Lock;
                ar & m_LookupId;
                ar & m_LookupName;
                ar & m_SequenceNumber;
                //reset old state for the case we want to continue working
            }
            BOOST_SERIALIZATION_SPLIT_MEMBER()
===============================================================

The class I serialize is part of a deep class hierarchy that I want to
serialize as a whole.
With the standard serialize() it seems to work, but now the compiler
complains ( when I
want to perform the actual serialization):

error C2662: 'void
jedox::palo::AbstractCache<C,Exception>::save<Archive>(Archive &,unsigned
int)' :
cannot convert 'this' pointer from 'const
jedox::palo::AbstractCache<C,Exception>' to
'jedox::palo::AbstractCache<C,Exception> &'

AbstractCache is the class containing the above load / save operations

kind regards,
Oliver
