logic:interate循环问题

Question

用logic：interate标签循环输出，里面有个属性值也是list，怎么循环取出这第二个list里的某个属性值？？

一直报 javax.servlet.jsp.el.ELException: The "." operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer.

从异常看，看看哪里是不是多了个点 (.)
