Label Height Incorrect

Question

I have some code that creates a label, then is supposed to use the height of that label to determine where to put another one below it.  The problem is that the height being returned is always 22 whether it's one line or two and changing the font size doesn't change it either.  These labels are being created in an array.  Here's some sample code:
Outside of Array:
var myFont:Font = new helvetica_bold();
var text_format:TextFormat = new TextFormat();
text_format.font = myFont.fontName;
text_format.size = 14;
text_format.align = "center";
Inside of Array:
//////// Add Label 1
var text_string1:String = xmlData.Product[i].name;
var label1:Label = new Label();
label1.move(xpos,ypos);
label1.width = 200;
label1.wordWrap = true;
label1.text = text_string1;
label1.autoSize = TextFieldAutoSize.CENTER;
label1.textField.antiAliasType = AntiAliasType.ADVANCED;
label1.setStyle("embedFonts", true);
label1.setStyle("textFormat", text_format);
addChild(label1);
//////// Add Label 2
var text_string2:String = xmlData.Product[i].brand;
var label2:Label = new Label();
trace(label1.height);        // This always returns 22
label2.move(xpos,ypos + label1.height);
label2.width = 200;
label2.wordWrap = true;
label2.text = text_string2;
label2.autoSize = TextFieldAutoSize.CENTER;
label2.textField.antiAliasType = AntiAliasType.ADVANCED;
label2.setStyle("embedFonts", true);
label2.setStyle("textFormat", text_format);
addChild(label2);
Because the labels can be one line or two lines, I need that height to be dynamically generated.  Any ideas on how to have the label height returned accurately?  Should I use a different text object instead?
Thanks!

i forgot to increment i in that loop:
var prevY:Number=0;
for(var i:uint=0;i<whatever;i++){
var l:Label=new Label();
// assign text and format
l.y=prevY;
prevY+=l.height;
// which will fail with components, use:
this.addEventListener(Event.ENTER_FRAME,f);
var prevY:Number=0;
var i:uint=0;
var l:Label;
function f(e:Event){
if(i<whatever){
if(l!=null){
prevY=l.height
i++;
l=new Label();
// assign text and format and this should be a function of i, so it will/may vary with each loop
l.y=prevY;
} else {
this.removeEventListener(Event.ENTER_FRAME,f);
