Apparently null_property_map is write-only, so it doesn't have a get() function; I hadn't realized that.  Please try dummy_property_map (from boost/property_map/property_map.hpp) instead, or if that doesn't work, static_property_map or ref_property_map from the same file.

With

dp.property("node_id", boost::dummy_property_map());

I get: "error: invalid use of void expression".

with

dp.property("node_id", boost::static_property_mapGraph::vertex_descriptor());

Try: std::string s; ... boost::static_property_mapstd::string(s) ... -- Jeremiah Willcock
