title: GWT validation that can change style of the field
body: <p>I'm looking for validation library for GWT that is able to change widget style on error. <br></p>
  
  <ol>
  <li>I haven't found it in GWT-Validation (maybe I missed something>.</li>
  <li>I found the framework that have the functionality GWT-VL (http://gwt-vl.sourceforge.net), but it is dead from 2009 (pure documentation, no maven repo working).</li>
  </ol>
  
  <p>Are there any more usable validation frameworks for GWT with that functionality ? </p>
