前台有一个自定义标签貌似得不到传过来的值

<#cms_category_list  siteId="${site.id}" categoryId="${category.id}" isNav="0"  var="category">
       <br>
       <a href="${category.url!}">${category.names!}</a>
       <br>
   </#cms_category_list>

提示

:变量未定义(VAR_NOT_DEFINED):site 位于9行 资源:/templates/www/sjw/index.html

${site.id}这种写法有问题吗？
