title: How can I reference the TextInput of an editable ComboBox?
body: <p>I have an editable ComboBox component and I want to reference the TextInput that is shown, in order to programmatically select the Text in it. This is very straightforward on a TextInput:</p>
  
  <pre><code>private function selectNameText():void
  {
      nameTextInput.selectionBeginIndex = 0;
  
      nameTextInput.selectionEndIndex = nameTextInput.text.length;
  }
  </code></pre>
  
  <p>But I can't find any way to access the TextInput of an editable ComboBox.</p>
