Boost multi_array question

Hi all, I've just decided to pick up boost for use in one of my programs, and I've been having trouble with initialising a multi_array. The problem that I've been having is trying to make a multi dimensional array of a class, something like this:

class foo
{
public:
foo(int _x){x = _x}
~foo(){}
private:
int x;
};

boost::multi_array< foo , 2 > array( boost::extents[100][100]);

I have no idea where to call the classes constructor, or how to make sure that there is enough memory allocated to hold it, any help at all appreciated.
:)

Shameless bump here, I really need to find this out.
If anythings unclear, please ask me to clarify :).

So far as I can tell, it's the default constructor or nothing at all.

Ugh, that's exactly what I didn't want to hear. If anyone knows of a way to use a non default constructor, please help :(

Hm, interesting omission. Perhaps you should bring this issue up on the Boost mailing lists.

I might just do that, I don't know about you people, but I make arrays/vectors of classes all the time, and after doing some reading into boost/multi_array, it seemed like the answer to a few problems that I'd been having. But seems like this was something that they either didn't think of, or there's something that I'm missing. Thanks for the help anyway guys.
