Errors when displaying TextArea

[dc2000]

I have the following code that is supposed to display a static uneditable and non-selectable text message on a Sprite:

import fl.controls.TextArea;

var rect1:Sprite = new Sprite();

rect1.graphics.lineStyle(4);
rect1.graphics.moveTo(0, 0);
rect1.graphics.lineTo(160, 0);
rect1.graphics.lineTo(160, 50);
rect1.graphics.lineTo(0, 50);
rect1.graphics.lineTo(0, 0);

var lbl1:TextArea = new TextArea();
lbl1.x = 4;
lbl1.y = 4;
lbl1.editable = false;
lbl1.text = "Label";
rect1.addChild(lbl1);


addChild(rect1);

when that is run I get the following error:

The stage also has a UIComponent button on it.

The FLA file is attached here as well.

Can someone tell me what is wrong here?

In addition to importing the TextArea component, you also have to have it in your library. So drag the TextArea component from the components panel to the library (or drag one to the stage and then delete it), and the error messages will go away.

What if I use TextField instead?
