freemarker嵌套循环怎么写5

     下面是JSP页面代码
<c:forEach var="each" items="${typeProList}" begin="0" end="0">
     <c:forEach var="product" items="${each.proList}" begin="0" end="1">
         <div class="bot_right_pro_1">
   <div class="pro_1_1"><a href="${pageContext.request.contextPath }/s/product.shtml?method=productinfo&proid=${product.id }"><img src="${pageContext.request.contextPath }<%=SConstants.CEM_UPLOAD_PRODUCT_PATH %>${product.picurl }" title="${product.name }" width="90" height="90"/></div>
   <div class="pro_title"><a href="${pageContext.request.contextPath }/s/product.shtml?method=productinfo&proid=${product.id }" title="${product.name}"><strong><shopping:TagUtil type="string" begin="0" end="5" target="${product.name}"/></strong></a></div>
   <div class="pro_title"><img src="${pageContext.request.contextPath}/images/huigou/icon_2.jpg" /><strong><span class="red">${product.hmprice }元</span></strong></div>
</div>
</c:forEach>
</c:forEach>
                   这是我根据以上写的ftl(freemarker 标签写的)
<#if typeProList?exists>
         <#list typeProList[0..0] as each>
            <#list each.proList[0..1] as product>
         <div class="bot_right_pro_1">
   <div class="pro_1_1"><a href="/huigou/s/product.shtml?method=productinfo&proid=${product.id }"><img src="/huigou<%=SConstants.CEM_UPLOAD_PRODUCT_PATH %>${product.picurl }" title="${product.name }" width="90" height="90"/></div>
   <div class="pro_title"><a href="/huigou/s/product.shtml?method=productinfo&proid=${product.id }" title="${product.name}"><strong><shopping:TagUtil type="string" begin="0" end="5" target="${product.name}"/></strong></a></div>
   <div class="pro_title"><img src="/huigou/images/huigou/icon_2.jpg" /><strong><span class="red">${product.hmprice }元</span></strong></div>
</div>
</#list>
</#list>
   </#if>

但是报错：list each.proList[0..1] as product [on line 24, column 37 in probottom.ftl]

问题补充：

蔡华江写道

<#list each.proList[0..1] as product>
改为
<#list (each.proList)[0..1] as product>
试试
