Description

Play the following mxml:

=======================================================
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="onCreationComplete()" xmlns:local="*">

<mx:Script>
<![CDATA[
[Bindable]
private var persona:Persona = null;

private function onCreationComplete():void

{ persona = new Persona("Sergio"); persona.nombre="Sergio"; persona.apellidos="Aguado"; }

private function onClick():void

{ var newPersona:Persona = new Persona("Pedro"); newPersona.nombre=null; newPersona.apellidos="Pol"; persona=newPersona; }

]]
>
</mx:Script>
<mx:Button click="onClick()" label="changePerson"/>

<mx:Label id="personNameLabel" text="

{persona.nombre}" />

<mx:RichTextEditor id="textEditor" width="100%" height="100%" htmlText="{personNameLabel.text}">
</mx:RichTextEditor>

<mx:RichTextEditor id="textEditor2" width="100%" height="100%" htmlText="{persona.nombre}

">
</mx:RichTextEditor>
</mx:WindowedApplication>
=======================================================

You will find that when the button is clicked and the value of the person is changed and it's name gets null the second
RichTextEditor doesn't update itself. However the label updates.

Workaround
Bind the expression to a label (and make it invisible) and a RichEditor to that label.
