Hello,

    When trying to serialize a STL map, doing the following (in Visual C++
7.1):

class Being
{
private:
    std::wstring Name, Description;
    friend class boost::serialization::access;
public:
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & this->Name;
        ar & this->Description;
    }
};

class Ecosystem
{
private:
    friend class boost::serialization::access;
    std::map<std::wstring,Being> Beings;
public:
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & this->Beings;
    }
};

...
ar & ecosystem;   // Making the serialization within some function (storing)
...

    I get this compile-time error:

"c:\Boost\include\boost-1_33_1\boost\serialization\access.hpp(109): error
C2039: 'serialize' : is not a member of
                 'std::map<_Kty,_Ty>' with
[_Kty=std::wstring,_Ty=Models::Beings]"

   Has anyone any ideas about the reason for this error?
   Thanking you in advance,

   David
