关于FreeMarker的list循环取值问题

我定义${item[0].items[0].name}可以正常取items[0]的name值，但是我要是循环遍历items中的name值，即

<#list item[0].items as x>
var listArray = [];
listArray[${x_index}] = "${(x.name)!""}";
</#list>
就会报错
Expected collection or sequence. item[0].items evaluated instead to freemarker.template.SimpleHash on line 81, column 24 in index.ftl.
想知道这个怎么操作？谢谢
我改为<#list ${item[0].items} as x>报的是这个错误：

Exception in thread "main" freemarker.core.ParseException: Encountered "{" at line 81, column 25 in index.ftl.
Was expecting one of:
"as" ...
"." ...
"[" ...
"(" ...
"?" ...
"!" ...
<TERMINATING_EXCLAM> ...

去看看freemarker表达式怎么用的就知道了，看是否正确，或者和其他表示方式有冲突吧。
