title: Spring MVC <form:errors/> tag doesn't find error messages
body: <p>I work with a front-end developer who writes JSP files. We have a form that is working correctly, except validation/binding/processing errors can't seem to be displayed with Spring's <code>&lt;form:errors/&gt;</code> tag.</p>
  
  <p>I've confirmed that the error is being set, and what is apparently the correct path for the errors.  Supposedly <code>&lt;form:errors path="*" /&gt;</code> should render them all, regardless of path, but it shows nothing.</p>
  
  <p>Do I need to get into the tag library source to deduce what's going wrong?</p>
