OMG am I going backwards now with code? Please see

programming flash
1 
var tf:TextField = new TextField();
var tfFormat:TextFormat = new TextFormat();
	tfFormat.size = 25;
	tf.defaultTextFormat = tfFormat;
	tf.text = "hiiii";
	addChild(tf);

That works fine… For 10 minutes though I had it like this and it wasn’t working:

var tf:TextField = new TextField();
          tf.text = "hiiii";
var tfFormat:TextFormat = new TextFormat();
	tfFormat.size = 25;
	tf.defaultTextFormat = tfFormat;
	addChild(tf);

Notice all I did was swap the tf.text placement. How in the heck is it not working in the second example? I mean am I just losing my noggin or what? Even in the adobe examples they have it set up like this. They have the text defined before the TextFormat just as I do in the second example. Unbelievable! lol Maybe flash has a bug?
