title: Setting up gwtupload with uiBinder
body: <p>I'm trying to setup the <a href="http://code.google.com/p/gwtupload/" rel="nofollow">gwtupload</a> widget with uiBinder and I'm having a hard time getting this configured.  </p>
  
  <p>I got the code working with the regular <code>gwt-fileUpload</code> widget, but I wanted the <code>gwtupload</code> because of it's richer functionality.  Here is what I did for the <code>gwt-fileUpload</code> widget:</p>
  
  <pre><code>    @UiHandler("calculateComplexityButton")
      void onClickCalculateComplexity(ClickEvent e){
          formPanel.setEncoding(FormPanel.ENCODING_MULTIPART);
          formPanel.setMethod(FormPanel.METHOD_POST);
          formPanel.setAction(UPLOAD_ACTION_URL);
          String fileName = fileUpload.getFilename();
          fileUpload.setName(fileName);
          formPanel.submit();
      }
  </code></pre>
  
  <p>I'm not seeing how to setup the same thing with <code>gwtupload</code>.  I'm seeing this error: </p>
  
  <pre><code>HTTP ERROR: 404 NOT_FOUND
  RequestURI=/servlet.gupld
  </code></pre>
  
  <p>I don't understand how to map the <code>gwtupload</code> widget to my servletPath, because I'm configuring it under uiBinder? </p>
