title: ExtJS combo box disabled properties not functioning
body: <p>I attempted to disable the combo box component with the disabled attribute however it's not working. The code is below:</p>
  
  <pre><code>xtype: 'bkl.exchange.ExchangeRFCombo',
  disabled: true,
  fieldLabel: 'Exchange',
  id: 'exchMapee',
  valueField: 'omsMappingCode',
  editable: false
  </code></pre>
  
  <p>The mode is remote and not local. So the values displayed by the combo box is from the database. Is there a solution to this problem?</p>
  
  <p>Your help is kindly appreciated.</p>
  
  <p>Thank You.</p>
