    a4j:outputpanel - Tomcat vs. Websphere Behavior (Exception)

      The following page features four panels with panels two thru four populated by an Ajax response. The page works running on Tomcat (JSF 1.1.x).

      When running on Websphere, a browser "refresh" of the page, or, selecting the dropdown from panel one causes an Error 500 with the exception noted at bottom.

      If the third panel code is removed:
      <a4j:outputPanel id="outputSummary" ajaxRendered="true">
      <h:outputText id="textSummary"
      value="Panel 3. #{DependentBean.displaySummary}" escape="false" />
      </a4j:outputPanel>

      THEN THE PAGE WORKS - both Ajax behavior and browser "refreshing" the page. Any ideas why the above code causes a problem with Websphere and not Tomcat???
