我想使用 ui:repeat 或任何其他迭代标记为数组列表中的每个项目显示多个组件一次。

<ui:repeat id="mandates" var="mandate" value="#{taxheadDirectDebit.mandates}">

我在这里取出了很多我的代码，所以可能有 un macthed div 等，但想法就在那里。
我有两个问题：
- 你可以看到一些组件有更改事件，这些事件会根据 id 呈现其他组件。这些在重复中不起作用
- 我正在使用 webflow 并将消息添加到消息上下文中，以便消息标签可以显示验证消息，但这些在迭代中也不起作用。
我试过 tr:iterator、c:forEach、a4j:repeat、tr:forEach。我很确定我正在尝试做的事情不可能像我尝试做的那样，所以如果有人有尝试实现类似的经验，我会很感激一些帮助。我无法更改我正在使用的 MVC 框架，但也许可以使用 jQuery。
