title: Open a new window Onclick of image button
body: <p>I am using primefaces 3.5, the latest release for our development work!
  Inside the prime face datatable , i have commandLink which is used to open a new window , based on the URL constructed with the request parameter.Attached the code for reference.</p>
  
  <pre><code>&lt;p:dataTable&gt;
  &lt;p:column style="text-align:center;"&gt;
  &lt;h:commandLink value="" action="#{claimStatusBean.npfInfo.handleNpf }" target="_blank" &gt;
  &lt;h:graphicImage library="images" name="star_small.png" rendered="#{claimStatus.npfProvider}"/&gt;
  &lt;/h:commandLink&gt;    
  &lt;/p:column&gt;
  &lt;p:dataTable&gt;
  </code></pre>
  
  <p>But when i click the action is never invoked.</p>
