Jens, the ReadablePropertyMap parameter has to be a class with the following typedef at least:
typedef value_type some_type;
Why?
http://www.boost.org/libs/property_map/ReadablePropertyMap.html says:
Associated Types Value Type boost::property_traits<PMap>::value_type The type of

property.
That's what these traits classes are for: external adaption.
You replied to the fixed version where I use property_traits.
Jens, I think that you are missing something. As for me, the property_traits class is just a way of uniform data manipulation. Your class has to be a model of this abstract concept. (To be a Read Property Map it is enough to have 3 typedefs and get() function, see Concept Checking Class in the documentation that you referred). --Dmitry
