title: Seam: Reset form validation after modalpanel closes
body: <p>Im struggling with the following problem:</p>
  
  <ul>
  <li>I have a modalPanel for adding a new person on my Richfaces view</li>
  <li>I have two buttons "Save" and "Cancel"</li>
  <li>Some input fields are required with required="true" attribute on h:inputText component</li>
  <li>when I leave one or more required fields empty and cancel the form/modalpanel, the modalpanel closes</li>
  <li>When I now want to add a new person, I instantiate a new Person object on my backing bean, reRender the elements in the modalPanel.</li>
  <li>ModalPanel opens up again</li>
  <li>Sometime it happens, that the failed validation on my first attempt to create a new person impeded the reRendering of the validation of my modalPanel input fields</li>
  <li>I see the new empty fields from my new person object, but the view has the validation error messages from the last attempt?</li>
  </ul>
  
  <p>So, how can I make sure to reset all backend logic, form and buttons by clicking the "Add Person" button?</p>
  
  <p>Thank you</p>
