Hi Sascha,

Here is a small example program I wrote that seems to do what you  
want.  The main difference is that it "gets" the property map
and places it in the dynamic properties at the same time:

#include <boost/graph/adjacency_list.hpp>
#include <boost/property_map/dynamic_property_map.hpp>

using namespace boost;

struct vertex_p {
   int foo;
   char bar;
};

int main() {

   typedef adjacency_list<vecS,vecS, directedS, vertex_p> graph_t;

   graph_t g;

   dynamic_properties dp;

   dp.property("foo",get(&vertex_p::foo,g));

}

HTH,
Ron
