[Boost-users] [BGL] Properties in a set-based adjacency list

Hello, How can I use an external property map with an adjacency list which uses a setS for the vertex list? I got property maps (with arrays as storage for the property values) working fine with a vecS adjacency list, but I can't seem to get them to work after changing the template to setS. I understand the reason is lack of automatic indexing, but don't know how to get around that. Using set/map for storage of property values would most convenient for me. On a similar note, perhaps it's possible to use a map to store the vertices, mapping ints to Vertex descriptors? (that was the original custom implementation of graph class which I'm porting to BGL). TIA, Greg
