title: RadioGroupFieldEditor setPropertyChangeListener
body: <p>I have a <code>RadioGroupFieldEditor</code> field in my application, this field is internally added to <code>FieldEditorPreferencePage</code> using <code>addField()</code> method.</p>
  
  <p>I have added <code>setPropertyChangeListener(new IPropertyChangeListener()</code> for the field, but the control is not going to <code>IPropertyChangeListener</code> when I select the value.</p>
