I defined an double array inside bundled vertex property, and have trouble finding ways of accessing it.

Neither can I find any where in the document an example on it. Your input will be much appreciated!

my graph is defined as follows:

struct Node
{
// this is hard to access
double mode[3];

};

struct Edge
{

//no problem access them
double nPixels;
unsigned short nTh;
};

typedef boost::adjacency_list<
boost::vecS, boost::vecS, boost::bidirectionalS,
Node, Edge> Graph;

//Graph object colGraph

Graph colGraph;

I have no problem with accessing the 'nPixels' in Edge property,

boost::property_map<Graph, double Edge::*>::type
ew = get(&Edge::nPixels, *colGraph);//edge weight

But I am in a great deal of trouble finding ways of accessing 'mode' in Node property.

//compiler error here
boost::property_map<Graph, double Node::*>::type
   nm = get(&Node::mode, *colGraph);//node mode
error message is :
//----------------------------------------------------
c:\...\xxx.cpp(236) : error C2440: 'initializing' : cannot convert from 'boost::property_map<Graph,Property>::type' to 'boost::bundle_property_map<Graph,Descriptor,Bundle,T>'
        with
        [
            Graph=boost::adjacency_list<boost::vecS,boost::vecS,boost::bidirectionalS,Node,Edge>,
            Property=double (Node::* )[3]
        ]
        and
        [
            Graph=Graph,
            Descriptor=boost::property_map<Graph,double Node::* >::descriptor,
            Bundle=Node,
            T=double
        ]
        No constructor could take the source type, or constructor overload resolution was ambiguous
//----------------------------------------------------

neither the following works(I added '[3]' in the parameter list):
boost::property_map<Graph, double Node::*[3]>::type
   nm = get(&Node::mode, *colGraph);//node mode

This time errors are raised in the 'property.hpp' file, they are:
