Boost Graph - Sub Graph Bundled Properties Error
Could someone explain with the code below generates an error? The code worked fine with a standard boost graph (ie not a subgraph<>)...... I can create the sub graph, but cannot access the bundled properties data: typedef adjacency_list<listS, listS, undirectedS, VertexData, property<edge_index_t, int, EdgeData> > GraphType; typedef subgraph<GraphType> SubGraphType; SubGraphType SubGraph; SubGraphType::vertex_descriptor V = add_vertex(SubGraph); SubGraph[V].ID=1; ////ERROR!!!!!! Sincerely, John

This was a bug in Boost 1.33.x; it has been fixed in Boost CVS, and the upcoming Boost 1.34.0. Cheers, Doug
I downloaded boost CVS last night and wrote a test program to verify this. The compile problems remain. What gives? Douglas Gregor wrote:

I have to execute myself in that I fixed my own problems. But there are 2 caveats in using bundled properties with subgraphs. First, it seems that its is required that the subgraph has an edge index property. Second, it is no longer possible to cast the vertex descriptor to integers, even when vecS is used.
