title: Conditionally rendering <h:commandButton> using <c:if>
body: <p>I am using jstl for small testing. And it is not working how it is supposed to work</p>
  
  <p>here is the small code:</p>
  
  <pre><code>&lt;c:set var="id" value="#{mBlog.blog.id}"/&gt;
                      ${id}    //printing  4  
                      &lt;c:if test="${id &gt; 0}"&gt;
                          &lt;h:commandButton value="Update" action="#{mBlog.update}"/&gt;  //is not rendered
                      &lt;/c:if&gt;
  
                      &lt;c:if test="${id == 0}"&gt;
                          &lt;h:commandButton value="Save" action="#{mBlog.save}"/&gt;  //is not rendered
                      &lt;/c:if&gt;
  </code></pre>
  
  <p>I do not know what is wrong. in the display i see only 4, nothing else.</p>
