title: Getting a field value from a custom control when there are multiple instances of the custom control
body: <p>I have an xPage with multiple instances of the same custom control.   How do I get to the value of a field on a specific custom control from a button on my xPage.</p>
  
  <p>Normally I would do something like:</p>
  
  <p>ctlName = "radioGroupCMBUAction";
  var changeType = getComponent(ctlName).getValue();</p>
  
  <p>If there was only one instance of the control.   How would I do this with multiple instances of the control?</p>
