Hi Frédéric, Could you post a short (but complete) program showing what you are trying to do? Thanks, Jeremy On Feb 9, 2004, at 3:41 AM, Frédéric Mayot wrote:

Hi,

I have a graph in the form of an adjacency_list with an internal property. I'm using vecS for both vertices and edges (and I don't want to use listS).

When I remove a vertex with remove_vertex(), it seems that my property map is invalidated. Can I remove the property (from the map) which corresponds to the deleted vertex ? Is there any solution ?

Thanks.

Fred
