title: JSP cif not working
body: <p>I have this code in my jsp file:</p>
  
  <pre><code>&lt;body&gt;
      &lt;c:if test="${!isActivityVP &amp;&amp; isBuy &amp;&amp; isOwner}"&gt;
          Hello
      &lt;/c:if&gt;
  &lt;/body&gt;                                                                                                                                      
  </code></pre>
  
  <p><code>isActivityVP</code> and <code>isBuy</code> and <code>isOwner</code> are all boolean values</p>
  
  <p>when I visit the page, however, I got this in the html:</p>
  
  <pre><code>&lt;body&gt;
      &lt;c:if test="false"&gt;
          Hello
      &lt;/c:if&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>What's wrong here?</p>
