Applying Transform Matrix

Question

I am applying a transform matrix to a UIComponent. The width
of the object changes appropriately when displayed; however, the
width property on the component is 0. Does anyone know why the
width property is not updated? Is the only way to retrieve the
actual width through the transform matrix? I used the following
code snippet.
Thanks for any input!

var comp:UIComponent = new UIComponent();
comp.graphics.lineStyle(3);
comp.graphics.drawRect(0,0,200,200);
this.addChild(comp);
trace("width before applying matrix = " + comp.width); //
width = 0
var matrix:Matrix = new Matrix();
matrix.a = 2;
comp.transform.matrix = matrix;
trace("width after applying matrix = " + comp.width); //
width still = 0 Why not 400?

I think we need to set the dimensions of the UIComponent as well. Check whether the code below works
var comp:UIComponent = new UIComponent();
comp.graphics.lineStyle(3);
comp.graphics.drawRect(0,0,200,200);
comp.width = 200;
comp.height = 200;
this.addChild(comp);
trace("width before applying matrix = " + comp.width); // width = 200
var matrix:Matrix = new Matrix();
matrix.a = 2;
comp.transform.matrix = matrix;
trace("width after applying matrix = " + comp.width); // width still = 200
