hi，    how to use filter attribute of the <dbform> tag, i use it like the following, but it doesn't work, why?      <db:dbform multipart="false" autoUpdate="false" followUp="/ODS_PORTCIRCUIT_list.jsp" maxRows="*" tableName="ODS_PORTCIRCUIT"               filter="CIRCUITID=<%=request.getParameter("CIRCUITID")%>">       above, request.getParameter("CIRCUITID") has values like 0 ,1....     when i use filter="CIRCUITID=0" instead, it works, why?
