[Boost-users] Serializing the same Objekt several times

At the moment I am working with XML serialization of Boost. I am
serializing my own classes which works well. But my objects are changing
often, for example:

class Modul
{
  public: setValue(int);
  private: int Value;
}

Modul* M = new Modul();

Now I wanna serialize M every time Value changes, so that I can save a
complete history of changes on M. But M is serialized only once, after
that I get this in my XML, although Value has changed:

<Modul class_id_reference="1" object_id_reference="_2"></Modul>

This is unusable for my purpose, so how can I stop that kind of
"linking" and serialize the Objekt every time completely?
