Hi all, I'm getting exhausted with trying to get a functioning test case. I'm attaching my code, which consits of two classses: the second class Route is having a const reference member to the first class Protocol. It seems that I am able to serialize the two classes correctly, however when I deserialize the reference member is set to NULL. What am I doing wrong? Further, I was trying to have save_construct_data(...const Route * t...) to access the private members of the class Route by making it friend of the class. However, doing so results in a compiler error. Any idea of how I am supposed to deal with that? Thank you very much! -- Marco Canini
