[Boost-users] Getting vertices names.

    Hi there!

May be I'm asking something unbeleivably stupid, but anyway here is my 
problem.
I need to get the names of all vertices in the graph (It is 
GraphvizDigraph), so
----------------------------------------------------
using namespace boost;
property_map< GraphvizDigraph,
                vertex_name_t>::type&
                vn = get(vertex_name, g);
graph_traits<GraphvizDigraph>::vertex_iterator i;

for(i = vertices(g).first; i != vertices(g).second; ++i )
{
        std::cout<< vn[*i]<<endl;
}
----------------------------------------------------

And here is the error I got:
----------------------------------------------------
c:\Documents and Settings\MAKC\My Documents\Visual Studio 
Projects\Graph\MyGraph.cpp(61) : error C2679: binary '<<' : no operator 
found which takes a right-hand operand of 
type 'boost::vec_adj_list_any_vertex_pa::bind_<Tag,Graph,Property>::value
_type' (or there is no acceptable conversion)
        with
        [
            Tag=boost::vertex_name_t,
Graph=boost::detail::subgraph_any_pmap::bind_<boost::vertex_name_t,boost:
:GraphvizDigraph,boost::detail::vertex_property_map<boost::GraphvizDigrap
h,boost::vertex_name_t>::Property>::Graph,
            
Property=boost::detail::vertex_property_map<boost::detail::subgraph_any_p
map::bind_<boost::vertex_name_t,boost::GraphvizDigraph,boost::detail::ver
tex_property_map<boost::GraphvizDigraph,boost::vertex_name_t>::Property>:
:Graph,boost::vertex_name_t>::Property
        ]
-----------------------------------------------------

Since this code is almost "CopyPasted" from the library example,
my beleif is that it should work. At what point I have to change my 
worldview? :)

Thanks in advance.
