   at
  javax.servlet.http.HttpServlet.service(HttpServlet.java:738)
  The code currently assumes that the portlet which received the
  action is on the currently selected page.
  This assumption however is no longer true if a selection change
  has taken place during the portlet action.

  action is on the currently selected page.

  change has taken place during the portlet action.

  occur by handling the selection change case properly.
