title: Apache Wicket Manually select a radio button along with its onEvent()
body: <p>Hi I'm new to Apache Wicket. I have a form and a Radio Group in it. After some form operation I want to keep a radioGroup to default selected value. I got it working somehow using</p>
  
  <pre><code>form.get( "radioChoices" ).setDefaultModelObject( "choice1" );
  </code></pre>
  
  <p>But 'choice1' has onEvent() method overridden to clear text fields and <code>setDefaultModelObject</code> doesn't calls choice1's onEvent() method. Is there any way to properly set radioGroup to 'choice1' that eventually calls its onEvent() method?</p>
