title: How do I bind to a combobox display value?
body: <p>How do I bind to a combobox's <em>name</em> (ie display text) to some other component?</p>
  
  <p>I have a combobox called 'combo', and I have a label in a panel somewhere else that updates itself with the combo display value. The two widgets are bound via a ViewModel.</p>
  
  <p>If I set the bindings like this :</p>
  
  <pre><code>combo.setConfig({bind: {value: bindName}};
  </code></pre>
  
  <p>then the label will show the <em>value</em> of the combo (ie. key).</p>
  
  <p>If I do this :</p>
  
  <pre><code>combo.setConfig({bind: {name: bindName}};
  </code></pre>
  
  <p>then I get this error message :</p>
  
  <blockquote>
    <p>"Cannot bind name on Ext.form.field.ComboBox - missing a setName
    method."</p>
  </blockquote>
  
  <p>I have gone through other getter/setter methods in combobox with no success, having tried :</p>
  
  <blockquote>
    <p>combo.setConfig({bind: {name: displayField}}; </p>
    
    <p>combo.setConfig({bind: {name: rawValue}};</p>
  </blockquote>
