[Boost-users] [BGL] How to use an array in bundled property?

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 modeerror 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: 
//----------------------------------------------------
