title: Configuring Play! Framework to show full stack trace
body: <p>Is there a way to configure <a href="http://www.playframework.org/" rel="noreferrer">Play!</a> to show a full stack trace on error on the dev error page?</p>
  
  <p>The default exception view is very nice, but useless if one uses stuff like <a href="http://google-collections.googlecode.com/svn/trunk/javadoc/com/google/common/base/Preconditions.html" rel="noreferrer">Preconditions</a>.</p>
  
  <p>I understand you can get it via the log, but it would be nice to see it on the dev error page.</p>
