ItemEditor validation question

Question

I have an app with a datagrid populate by items dragged into
it. I have an object method that adds up the quantities of the
dropped objects and displays an error in they exceed the amount
defined in the object's properties. Works fine.
However, now I need to include data checking on a PER ITEM
level; that is, the XML entries for each grid item has its own min
and max qty, not just the list as a total. Can anyone recommend a
strategy for updating my old code to accomodate this?
A typical entry is <item ln1="Bacon" minQy="1/2" maxQy="1"
qty="1" units="lb." sn="bacon" />
I create each list item with: private var _list2 : List = new
List(0,1,.25,.25,"lbs","Meats") and then check the list with
_errQty = _list2.checkTotal(app._chosen2);
The list object:
quote:
public class List extends Object {
import mx.collections.*;
include "DialogStrings.as";
// CONSTRUCTOR
function
List(_minC:Number,_maxC:Number,_minQ:Number,_maxQ:Number,_un:String,_ingName:String){
_minChoices = _minC;
_maxChoices = _maxC;
_minQty = _minQ;
_maxQty = _maxQ;
_units = _un;
_shortName = _ingName;
// PRIVATE VARIABLES
private var _minChoices : Number;
private var _maxChoices : Number;
private var _maxQty : Number;
private var _minQty : Number;
private var _units : String;
public var _shortName : String;
// checks the total quantities, returns error string
public function checkTotal(_arr:ArrayCollection) : String {
var _errType:String = "";
var _n:Number = getTotal(_arr)
if (_n > _maxQty) {
_errType = "over";
else if (_n < _minQty){
_errType = "under";
} else {
_errType = "";
switch (_errType){
case "over":
return getMaxQtyError();
break;
case "under":
return getMinQtyError();
break;
case "":
return "";
trace("Quantity OK");
break;
default:
return "";
trace("no matching error condition");
break;
// adds up the quantities, returns sum
private function getTotal(_arr:ArrayCollection) : Number {
var _sum : Number = 0;
var _length : Number = _arr.length;
for(var i:Number=0; i<_length; i++) {
var _item : Object = _arr.getItemAt( i );
var _value : Number = _item["@qty"];
_sum += _value;
return _sum;

Thanks I'll just have to wait till I get the email back.
I had a look now and it appears Apple have added Macbook Air to the list. I was confused for quite some time as to what to choose when Air wasnt on the drop down menu.
As long as the serial number dictates the vaildity of my request rather than the model then I'm happy.
thanks
