Nested vectors and TTree::MakeProxy

Hi roottalk,
I have a tree containing a class A which looks like this:

class A : public TObject
{

	vector<B> b;
	[...]

where B has a member which is a vector<double>:

class B : public TObject
{

	int i;
	vector<double> d;
	[...]

I am trying to access A via TTree::MakeProxy. My question is, how do I access a particular element of the vector d? That is, what is the proxy equivalent of:

A a;
a.b[1].d[2];

I see that the equivalent of a.b[1].i is proxy.b.i[1], but how do I get what I want for the member d?

Thanks,
