can't reference iteration variable in Thymeleaf

I try to iterate a list of items using th:each,

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

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

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'item' available as request attribute

when I use th:field to access it, where did I do wrong?

Solution

  • Something like this could work:

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