我一次又一次地收到同样的异常。比较没有for="#{choiceRadio.clientId}"的异常和 hmtl-output似乎告诉我绑定有效。但事实并非如此，我觉得我错过了一些巨大的东西。

编码： 

    <p:selectOneRadio binding="#{choiceRadio}" value="#" layout="custom">
        <f:selectItems value="#" />
    </p:selectOneRadio>

    <h:panelGrid columns="1">
        <ui:repeat var='choice' value='#{item.items3}'>
            <p:radioButton for="#{choiceRadio.clientId}" />#{choice.name}
        </ui:repeat>
    </h:panelGrid>

</h:form>

例外：

没有 ui:repeat 我没有任何异常，但没有 ui:repeat 我也没有任何内容： 

    <p:selectOneRadio  id="myRadio" value="#{cartBean.selectedChoice}" layout="custom">
        <f:selectItems value="#{item.items3}" />
    </p:selectOneRadio>

    <h:panelGrid columns="1">

            <p:radioButton for="myRadio" value="hh" itemIndex="0"/>

    </h:panelGrid>

</h:form>

的for属性radioButton必须是id它selectOneRadio所指的。

添加id到您的selectOneRadio并在按钮中引用它：

<p:selectOneRadio id="myRadio" binding="#{choiceRadio}" value="#" layout="custom">
    <f:selectItems value="#" />
</p:selectOneRadio>

<h:panelGrid columns="1">
    <ui:repeat var='choice' value='#{item.items3}'>
        <p:radioButton for="myRadio" />#{choice.name}
    </ui:repeat>
</h:panelGrid>

编辑

您可能需要在 element 之前添加所有NamingContainers的 id ，例如：。ViewRootidfor="form_id:myRadio"

如果不确定元素的确切绝对值id是什么，请在 FireBug (Firefox) 或开发人员工具 (Chrome) 中查看它，或id在 html 输出源中搜索给定的（在本例中为“myRadio”）并跳过可能的数字-之间。

所以这

id="iterateCategories:0:iterateItems:2:lightForm:radioForm"

会成为

iterateCategories:iterateItems:lightForm:radioForm

作为你的绝对身份。
