title: JSP <c:out/> - The default attribute doesn't work?
body: <p>I'm having trouble with the default attribute of the JSP/JSTL tag . The value given for the default-attribute is not displayed.</p>
  
  <pre><code>&lt;% @ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%&gt;
  
  &lt;c:out value='value' default="defaultValue"/&gt; 
  </code></pre>
  
  <p>=> Displays value </p>
  
  <pre><code>&lt;c:out value='' default="defaultValue"/&gt;
  </code></pre>
  
  <p>=> Displays nothing.. // Should have been <code>defaultValue</code></p>
  
  <p>Why doesn't this work?</p>
