内部UI:repeat不会绑定到嵌套UI:repeat中的bean [英] Inner UI:repeat does not bind to a bean in a nested UI:repeat

问题描述

我正在使用嵌套的ui:repeats显示我的数据.外部UI:repeat可以正常工作并绑定到bean，但是内部UI不绑定到bean.总而言之，我想显示一个人的列表，其中每个人都有一个名字和一个电子邮件地址列表.这是我的代码:

I am using nested ui:repeats to display my data. the outer UI:repeat works and binds to bean just fine, but the inner does not bind to the bean. In sumary, I would like to display a list of people where each person has a name and a list of email addresses. Here is my code:

<ui:repeat value="#{myFamily.personList}" var="eachPerson" >
  <tr:panelCaptionGroup captionText="#{eachPerson.name}" styleClass="fullWidth">
    <h:inputText value="#{eachPerson.age}" styleClass="fullWidth" />    
    <ui:repeat value="#{eachPerson.emailList}" var="eachEmail" >
      <h:panelGrid columns="2">
        <h:outputLabel value="#{eachEmail.type}:" styleClass="darkBlue label" />
        <h:inputText value="#{eachEmail.email}" maxlength="40" size="38" />
      </h:panelGrid>
    </ui:repeat>
  </tr:panelCaptionGroup>
</ui:repeat>

与personList的绑定很好，因为我通过更改每个人的年龄进行了测试，并且在提交后更改了模型.但是，无论我在屏幕上进行什么更改，电子邮件列表都不会更改.

The binding to the personList was fine since I had tested by changing the age of each person and the model changed after I submit. However, the emails list is not changed no matter what I change on the screen.

请帮助！我正在使用JSF，Spring Web Flow，Facelets和Trinidad.

推荐答案

感谢您的快速响应.在Google花了一些时间后，我发现嵌套的UI:repeat是很好的支持.您可以使用其他替代方法，例如tr:iterator，c:forEach和/或tr:forEach.

Thank you for you quick response. After spending some time on google, I found out that nested UI:repeat is well suported. You can use different alternatives like tr:iterator, c:forEach, and/or tr:forEach.

我想澄清的一件事是，c:forEach和ui:repeat确实将值绑定到支持bean，并且在jsf和facelets中得到了很好的支持.

One thing I'd like to clearify that c:forEach and ui:repeat do bind values to the backing beans and well supported in jsf and facelets.
