使用<c:forEach>报"找不到相关属性""的异常

<%--
写了如下一段代码,报如下错误
javax.el.PropertyNotFoundException: Property 'id' not found on type java.lang.String
检查好几遍,clientPageModel.list明明就有id属性

错误原因,clientPageModel.list忘了写在${}里面
 --%>
<c:forEach items="clientPageModel.list" var="client">

<tr>
	<td class="rd8">
		<input type="radio" name="selectFlag" value="${client.id }"
			onDblClick="selectOk()">
	</td>
	<td class="rd8">
		${client.clientId }
	</td>
	<td class="rd8">
		${client.name }
	</td>
	<td class="rd8">
		${client.clientLevel.name }
	</td>
</tr>
