*NUMBER2DISCUSS* unfortunately is useless since it is the catch-block and not
where it occurs:
      if (pageContext != null) pageContext.handlePageException(t);
    } finally {
      if (_jspxFactory != null) _jspxFactory.releasePageContext(pageContext);
    }

Suggestion: add a printStackTrace such that I can find which line is the
offending one!
