我想使用ui：repeat或任何其他迭代标记来显示一次组件 对于数组列表中的每个项目。
<!-- print multiple mandates -->
<ui:repeat id="mandates" var="mandate" value="#{taxheadDirectDebit.mandates}">
<a4j:region id="remittanceDetailsSection"
rendered="#{(taxheadDirectDebit.accountFinancialInfo.registration.type != 'PREM') or (taxheadDirectDebit.accountFinancialInfo.registration.type != 'VAT')}">

我已经在这里取出了很多代码，所以可能会有未定义的div等，但这个想法就在那里。
我有两个问题：
我试过tr：iterator，c：forEach，a4j：repeat，tr：forEach。我很确定我正在尝试做的事情是不可能的，因为如果有人有尝试实现类似的经验我会很感激一些帮助。我无法改变我正在使用的MVC frameowork，但也许可以使用jQuery。
答案 0 :(得分：0)
我通过在重复之外移动ajax区域并在整个区域上调用render来解决这个问题。我不知道，但我找到的最快的解决方案。
在消息方面，我只需将正在迭代的列表中的项目索引添加到消息中。
"remittanceDetails:mandates:"+taxhead.getMandates().indexOF(mandate)+":remittanceAmount" + frequency.getMonth().getCode()
JSF照顾其他人。
