[Boost-users] [BGL] get_property does not seem to return a reference

Hi,

I use an additional map as a graph property. The manual says  
get_property returns a reference:

template <class GraphProperties, class GraphPropertyTag>
const typename graph_property<adjacency_list, GraphPropertyTag>::type&
get_property(const adjacency_list& g, GraphPropertyTag);

so I would expect I could simply change the map but and forget about  
it. This does not work and I have to use set_property after my  
changes which means I have been working with a copy.

Any ideas why this happens?

Cheers, Torsten
