GetCharBoundaries equivalent in spark text components

Question

Is there an easy way in the new text components to do what getCharBoundaries (in flex.TextField) does? (i.e. get the position of a particular character within a text field)
So far, all I've come across is getAtomBounds in the TextLine class. But I'm not sure how to make use of this from the starting position of a TextArea or other spark component. Before I go delving into this further, is there an obvious way to do this that I've missed. And if not, can anyone give me a lead on how to make use of getAtomBounds from a RichText or other component.
Any help greatly appreciated.

dave,
Good catch! Can you please file a bug at http://bugs.adobe.com/flex/ and include a simple test case (actually, I was able to repro with the test case below if you want to use that code)? (and then post the bug number here so I can subscribe and assign to the correct person).
You can see from the code below that the flowComposer seems to be null by default, but if you edit the code you will get a flowComposer object back.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/halo">
    <s:layout>
        <s:VerticalLayout paddingLeft="20" paddingTop="20" />
    </s:layout>
    <fx:Script>
        <![CDATA[
            import mx.utils.ObjectUtil;
            private function init():void {
                debug.text = ObjectUtil.toString(richEdTxt.textFlow.flowComposer);
                btn.enabled = false;
        ]]>
    </fx:Script>
    <s:RichEditableText id="richEdTxt" change="btn.enabled = true;">
        <s:textFlow>
            <s:TextFlow>
                <s:p>The quick brown <s:span fontWeight="bold">fox jumps over</s:span> the lazy dog</s:p>
            </s:TextFlow>
        </s:textFlow>
    </s:RichEditableText>
    <s:Button id="btn" label="get flowComposer" click="init();" />
    <s:TextArea id="debug" width="550" height="300" />
</s:Application>
Thanks,
Peter
