title: Flex: Is there a way to bind ComboBox's selectedItem to a variable?
body: <p>OK I have a ComboBox, the dataProvider is an array of objects with label properties that give the ComboBox the list of options.</p>
  
  <p>Is there a way I can have a variable like mySelectedItem, and bind the ComboBox's selectedItem to it so that if it changes, the ComboBox's selectedItem will change to whatever it is?</p>
  
  <p>I hope this makes sense.</p>
  
  <p>Thanks!</p>
