Re: [Boost-users] issues with setting properties on reverse graph

in the first example that i posted i made the following change to the
definition of reverse_graph

typedef reverse_graph<graph_t, graph_t&> reverse_graph_t;
and now setting the name property on reverse graph works. accessing it using
the original graph also works.

However in my app which uses a new property defined by me the new typedef
still throws at runtime
I will work with it a little more and if I can't figure it out will let you
know

Thanks for the help
