java - can't reference iteration variable in Thymeleaf -

i try iterate list of items using th:each,

<div class="row" th:each="item : *{items}">   <input type="text" th:field="item.name"/> </div> 

it works if access iteration variable using th:text, throws

java.lang.illegalstateexception: neither bindingresult nor plain target object bean name 'item' available request attribute

when use th:field access it, did wrong?

something work:

<div class="row" th:each="item, stat : *{items}">   <input type="text" th:field="*{items[__${stat.index}__].name}"/> </div>
