Add TextLayout Component to root stage

Hi Guys,

do you know why this code doesn't work? The code is in the main timeline, first fotogramme. I have TextLayout in my library.

import fl.controls.*;

var tt:TextLayout = new TextLayout();

this.addChild(tt);

tt.x = 0;
tt.y = 0;
tt.width = 200;
tt.height = 200;

Get this error:

ReferenceError: Error #1065: Variable TextLayout is not defined.

ReferenceError: Error #1065: Variable ComponentShim is not defined.
