title: Primefaces p:confirmDialog inside tabView
body: <p>I now have problem with using confirmDialog inside tabView.
  Here is my confirmDialog</p>
  
  <pre><code>&lt;p:confirmDialog global="true" showEffect="fade" hideEffect="explode"&gt;
      &lt;h:form&gt;
          &lt;p:commandButton value="Yes" type="button"
              styleClass="ui-confirmdialog-yes" icon="ui-icon-check" /&gt;
          &lt;p:commandButton value="No" type="button"
              styleClass="ui-confirmdialog-no" icon="ui-icon-close" /&gt;
      &lt;/h:form&gt;
  &lt;/p:confirmDialog&gt;
  </code></pre>
  
  <p>In the 1st tabView, I have a button with confirmation</p>
  
  <pre><code>&lt;p:commandButton value="Import" icon="ui-icon-arrowrefresh-1-w"
      update=":form:growl"&gt;
      &lt;p:confirm header="Confirmation" message="Are you sure?" /&gt;
  &lt;/p:commandButton&gt;
  </code></pre>
  
  <p>In the 2nd tabView, I have exactly that button.</p>
  
  <p>And now my problem is: In the 1st tab, my confirmDialog have full text as I want: header and message, however in the 2nd tab, the header and message all become "null". Only button yes and no of confirmDialog still work. I don't know what is happening, please help me, how to make confirmDialog display full content in all tabView</p>
