I was searching the forum/list to find a solution for my problem and found
this thread.
My problem is exactly the same, since I changed from adjacency_list to
subgraph, I can't get my property_maps working.

I searched for hours without success, so I every hint is welcomed...

Unfortunately, my only attempt to use the subgraph stuff was unsuccessful, so I don't have much experience with it. Hopefully, somebody else will be able to answer this.
