hi,
i'm using the boost graph library and i'm trying to find the incident edges of one vertex of the following graph:

    typedef boost::adjacency_list<
        boost::vecS,                //  The container used for egdes
        boost::vecS,                //  The container used for vertices
        boost::bidirectionalS,      //  bidirectional edges
        Vertex,                     //  The type that describes a Vertex.
        Edge                        //  The type that describes an Edge
    > Graph;

if i try to find the incident edges now, the message "Interpolation failed" is printed. any suggestions?
here the code to find the incident edges:

    Graph::in_edge_iterator edgeIt, edgeEnd;
   tie(edgeIt, edgeEnd) = in_edges(vID, m_Graph);

thanks in advance,
peter
