[flexcoders] Actionscript accessing array of objects problem

[TCash21]

Hi all,
I'm having a problem accessing the items in an "array of Items"
Here's the code that initializes it

private var _edges: Object = new Object(); // map of id -> (map of id
-> 0)


Here's the function that returns the array
/***  Get an array of all the items that a given item is linked to.
*
*  @param id any String
*
*  @return an array of Items
*/

public function neighbors(id: String): Object {
    return _edges[id];
}

I've tried using 
for each (var i:Item in items.neighbors(id))
{
   statements...
}

I can't seem to access the items at all.  I've also tried omitting the
'each'.  

Any ideas?
Thank you!
