title: c:if test condition actually regular expression?
body: <p>I try to use condition</p>
  
  <pre><code>&lt;c:when test="${game.duration!='0:00'}"&gt;
  ...show rows
  ... 
  </code></pre>
  
  <p>The duration here is String, and condition should be true when the String does not match 0:00. This isn't working however! When I put </p>
  
  <pre><code>&lt;c:when test="${game.duration=='0:00'}"&gt;
   ... show rows
  </code></pre>
  
  <p>Rows are hidden, even if the duration value would be etc. 5:45. Is condition actually regular expression? How to fix this?</p>
