Embed fonts on classic TextField doesn't work, even with TextFormat applied

Hi.

I created an Item that extends MovieClip and that has a TextField on it where it where it will display the item's name. I want to embed the font but I'm having trouble because the text won't display.

I read the embedFonts description (http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/text/TextField.html#embedFonts) and I have formatted the TextField via a TextFormat instance with my chosen font.

My code:

import flash.display.MovieClip;     import flash.text.AntiAliasType;     import flash.text.TextField;     import flash.text.TextFieldAutoSize;     import flash.text.TextFormat;         public class Item extends MovieClip {                 private var _sName:String = "";         private var _txtName:TextField = new TextField();         private var _nColor:uint = 0xAACC00;         private var _tfText:TextFormat = new TextFormat();                 public function Item(s:String) {             //also tried embedding here but got the same result             _txtName.text = s;             _txtName.autoSize = TextFieldAutoSize.RIGHT;             _tfText.font = "Helvetica";             _tfText.size = 30;             _tfText.color = _nColor;             _txtName.setTextFormat(_tfText);             _txtName.antiAliasType = AntiAliasType.ADVANCED;             _txtName.embedFonts = true;                                     addChild(_txtName);         }

If I remove the embed part the text shows correctly. I'm at a loss, what order of elements do I need to use to embed the font correctly?

Thank you.
