title: Struts action called twice -
body: <p>When I submit a form to the browser,the form is submitted twice.The access log shows there are two requests arise at the same time.Two different threads executing it.</p>
  
  <p>The thing is,the first request contains the attribute values that the user entered while the second request call contains only null values in request object.</p>
  
  <p>Not all the times this issue occur.It happens only sometimes and not reproducible at all.Both in IE8 and IE9,I got these issues.</p>
  
  <p>Do anyone know why does it happen? </p>
