title: h:outputLabel not showing anything
body: <p>The problem that I am facing is that after I click on the <code>h:commandLink</code> button the <code>h:outputLabel</code> isn't showing anything. I have used selectedUser to store the value when the form is submitted but it seems selectedUser is not storing any value.</p>
  
  <p>1)Here is the xhtml file.</p>
