Was mache ich falsch?

template<class T>
class Binder
{
public:
    static std::vector< Binder< T >* > all;
    Node<T>* from;
    Node<T>* to;
    Binder(Node<T>* fnode, Node<T>* tonode)
    {
        from = fnode;
        to = tonode;
        Binder<T>::all.push_back(this);
    }
};

std::vector<Binder<int>*> Binder<int>::all = std::vector< Binder<int>* >(); //here it is

Vielen Dank.
