How to calculate the real height of the text in RichEditableText control?

Question

Hello,
I created a new component by extending the RichEditableText control.
When I try to get the value of contentHeight propery of this class even after compositionComplete event has fired, I get incorrect content height (so called "estimated" height). I was able to obtain the correct value only ater I set verticalScrollPosition to a value beyond this estimated content height thus causing the class to calculate real text height. Here is a code snippet.
public class ViewerController extends RichEditableText
public function loadText(){
   var tf:TextFlow = TextConverter.importToFlow(LONG_XML_FILE_WITHOUT_PICTURES_GOES_HERE as XML, TextConverter.TEXT_LAYOUT_FORMAT);
   //Events  
   tf.addEventListener(CompositionCompleteEvent.COMPOSITION_COMPLETE, compositionComplete);
   tf.addEventListener(StatusChangeEvent.INLINE_GRAPHIC_STATUS_CHANGE, pictureLoaded);
   this.textFlow = tf;  
   this.verticalScrollPosition = 0;  
   this.textFlow.flowComposer.composeToPosition(); // I assume this makes the control calculate the real size of the text
private function pictureLoaded(event:StatusChangeEvent):void {
private function compositionComplete(event:CompositionCompleteEvent):void {     
But what if I want to know the real height BEFORE I scroll to the very bottom of the text (or before even displaying this component)?

SDN is not your code factory, please research yourself before posting, maybe ask whoever handed you this requirement?
