>>What do you mean "children"? How are they represented by properties.

typedef subgraph< adjacency_list<vecS, vecS, undirectedS,
   Vertexp, property< edge_index_t, unsigned int, Edgep > > > Graph;

This is the property of every graph even the main graph and children.

I am creating children like this:

    Graph g; // main graph

   //graph children

   Graph& g1=g.create_subgraph();
    Graph& g2=g.create_subgraph();
    Graph& g3=g.create_subgraph();

That is the way that properties are supposed to work in filtered_graphs.

When I filter these graphs using the predicate, I can access the edges and vertices (as if it is a whole single graph) from filtered graph. But somehow filtered graph is forgetting that it is made of 3 subgraphs, i.e, I cannot access children of filtered graph . For example consider G is the filtered graph, I cannot access children through iterators.

tie(c1,c2)= G.children();
