title: wicket - two submit buttons with different validation
body: <p>I am using two AjaxButton for the same grid where both of them are not in the form but attached to it.</p>
  
  <pre><code>activateButton = new AjaxButton(ACTIVATE_BUTTON, grid.getForm())
  
  blockButton = new AjaxButton(BLOCK_BUTTON, grid.getForm())
  </code></pre>
  
  <p>my problem is trying to give each one of them different validation, when the form is submitted i am getting all the buttons validation instead of getting just one of them as I want.</p>
