title: <rich:tabPanel> not switching
body: <p>I have a <code>&lt;rich:tabPanel&gt;</code> and inside it I have three <code>&lt;rich:tab&gt;</code>,but tabs are not changing automatically whenever I'm clicking the next button for switching from one tab to another.Validation checking  is performed correctly and I have put condition on rendered property of <code>&lt;rich:tab&gt;</code>,that is also working correctly whenever I'm clicking the next Button 2nd tab is comming,but I need to click it through mouse for viewing its components,this should happen automatically as per the property of <code>&lt;rich:tab&gt;</code>.</p>
  
  <p>can anyone has any solution to this?</p>
  
  <pre><code>&lt;rich:panel header="My Claim &gt; New Claim" headerClass="header-left" style="border:0;text-align:left;width:910px"&gt;  
      &lt;rich:tabPanel  selectedTab="#{billController.currentTab}" id="tabPanel"&gt;
          &lt;!-- first default panel --&gt;
          &lt;rich:tab header="Step 1" name="fisrt" id="tab1"&gt;
              &lt;h:commandButton value="Next" action="#{billcontroller.saveData}"/&gt;
          &lt;/rich:tab&gt;  
      &lt;/rich:panel&gt;
  
  &lt;rich:tab header="Step 2"  rendered="#{billController.uploadEnabled}" name="second"&gt;
  
  &lt;/rich:tab&gt;
  </code></pre>
