The requested list key 'depList' could not be resolved as a collection/array/map/enumeration/iterato

错误提示:

Caused by: tag 'select', field 'list', name 'emp.dm.uuid': The requested list key 'depList' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

原因之一:

       后台的数据类型(比如时间)不匹配,可以不输入数据直接提交,如果正常,说明是某个数量类型不匹配,然后一次只输入一个数据,看输入了哪个数据后出错.

原因之二:

list中数据不存在(往往伴随java.io.IOException: Stream closed)
