title: Displaying part of text in RichText in bold font
body: <p>How do you make some parts of <a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/RichText.html" rel="nofollow">spark.components.RichText</a> bold?</p>
  
  <p>In my Flash / ActionScript 3 programm I have been just using <strong>htmlText</strong> property of a <strong>TextField</strong>, and set it to 1 2 &lt;b&gt;3&lt;/b&gt; - but now I'm trying to port my program to Flex 4.5.</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>I'm trying:</p>
  
  <pre><code>myRichtText.textFlow = TextConverter.importToFlow('1 2 3 &lt;s:span fontWeight="bold"&gt;4 5&lt;/s:span&gt;', TextConverter.TEXT_LAYOUT_FORMAT);
  </code></pre>
  
  <p>but nothing is displayed. I'd prefer not to use RichEditableText or TextArea.</p>
