[Boost-users] Storing vertex descriptors when removing a vertex

Hi all, I am using the boost graph library for my project and encountered a small problem I don't know how to solve. I had to keep in an extern storage some of the vertex_descriptor in order to have access to their adjacent vertices and their properties. But as it is written in the boost documentation, when I remove a vertex, the vertex_descriptors change and I am not able to keep the right ones in my storage. Is there something else apart from vertex_descriptor that won't change but from which I could also access adjacent vertices and properties ? Thank you in advance for your help. Orianne
