title: Passing a value of a component from one custom control to the other
body: <p>I have two custom controls, CustomControlBody    and CustomControlTitle.</p>
  
  <p>CustomControlBody has a radio button.  CustomControlTitle has a computed field based off of the value of the radio button in CustomControlBody.   </p>
  
  <p>If CustomControlTitle is placed within CustomControlBody then the computed field in CustomControlTitle can see the value of the radio button on CustomControlBody just fine.</p>
  
  <p>But for flexibility of design, I want to be able to place CustomControlTitle and CustomControlBody separately on the xPage.  But when I do this, CustomControlTitle does not seem to be able to see the radio button in CustomControlBody.</p>
  
  <p>How can I pass the value of the radio button in CustomControlBody to the computed filed in CustomControlTitle?</p>
