Take a look at the IViewCursor interface...
private function getItemInCart(item:ShoppingCartItem):ShoppingCartItem{
cursor = aItems.createCursor();
sortItems();
var itemToFind:Object = new Object();
itemToFind.product = item.product;
ar found:Boolean = cursor.findFirst(itemToFind);
f(found){
ar sci:ShoppingCartItem = cursor.current as ShoppingCartItem;
}else{
return null;
}
return sci;
}
does just what you are looking for without a lot of hassle
