Hello Jeremy,
Thank you for your quick answer. Unfortunately I'm not so experienced
with these property maps. Could you give me a hint how to wrap this
iterator_property_map around my vector::iterator?
Yours truly,
Marc Wintermantel

Hi Marc,
I think your problem is that BGL has get() and put() property map
functions defined for pointers, but vector::iterator is not guaranteed
to
be a pointer.
The fix is to wrap vector::iterator using the iterator_property_map
class.
Cheers,
Jeremy
