The problem is he is calling validateNow() on the text.changetextViaAS.validateNow(); // really just for kicks, it doesn'ttovalidateNow(); // really just for kicks, it doesn't
and you will see the tracenulltextViaMXML.width = 255textViaMXML.measuredWidth = 255textViaMXML.textWidth = 97textViaAS.width = 306textViaAS.measuredWidth = 306textViaAS.textWidth = 97This is becasue you are now calling validateNow() on the Application component.
Anyway, what he is doing is going against the grain. I don't think he fully understands what 'width' is. In this case measuredWidth IS the width since you didn't explictly call width.The ONLY reason width is even set in the 'callLater()' pass is becasue the Application set the width in it's setActualSize() call ON the Text component by USING the Text component's measuredWidth property. ;-)
:) This takes a little mind bending to understand. width property doens not always mean something. It depends on the contenxt metrics of the component's state.Peace, MikePS Everything is working the way it is supposed to, again, width is not 'god' anymore. measuredWidth is.

Nope, it doesn't. It returns 0.
If you use callLater, all values are returned correctly.
