    std::string name;
public:
    Way();
    Way(const Way& orig);
    void SetName(std::string name) { this->name = name; }
    std::string const & GetName() const { return name; }
    void SetId(std::string id) { this->id = id; }
    std::string const & GetId() const { return id; }

        return singleton;
    }
    void SetOnGoingWay(Way onGoingWay)  { this->onGoingWay = onGoingWay;  }

Way wayNode
wayNode.SetId("1234");
wayNode.SetName("jan");
AreaDataRepository::Instance().SetOnGoingWay(wayNode);
std::cout<<"Id ->>>>>>>>>>>>>" <<AreaDataRepository::Instance().GetOnGoingWay().GetId() << std::endl;
std::cout<<"Name ->>>>>>>>>>>>>" <<AreaDataRepository::Instance().GetOnGoingWay().GetName() << std::endl;


but this print nothing and i try to debug and get the values, vales are empty for OnGoingWay.
I need some help to sort out this.
