[急]在s:iterator进行判断.在线等
Java code

<select id="goodsTypeId" >
    <s:iterator id="gType" value="#request.listGoodsTypeData" status="index">
    <option id="${index}" <c:if test="${gdType.id == 3} "> selected="true" </c:if> >${gType.name }</option>
        </s:iterator>
        </select>




这里面的C:IF完全无效.请问是什么原因

原本的判断应该是这样的
 <c:if test="${gdType.id == goodsData.goodsTypeId}">
两个ID值是必然有相当的.但是却没有效果.如果单独拿出来不在<s:iterator >中就行
