logic:equal 做下拉框定位的问题

<select name="severity" >         <option value="-1">风险等级</option>          <logic:present name="sList" scope="request">           <bean:define   id= "seletedId"   name="searchVulForm"   property="severity"/>             <logic:iterate id="Severity" name="sList" type="com.risinginfo.rul.config.bl.Severity" indexId="counter">            <logic:equal name="Severity" property="id" value='${seletedId}'>             <option value='<bean:write name="Severity" property="id"/>' selected="selected" ><bean:write name="Severity" property="severity"/></option>            </logic:equal>            <logic:notEqual name="Severity" property="id" value='${seletedId}'>             <option value='<bean:write name="Severity" property="id"/>'  ><bean:write name="Severity" property="severity"/></option>            </logic:notEqual>           </logic:iterate>          </logic:present>         </select>
