我一直接受同样的异常。对于=“＃{choiceRadio.clientId}”比较异常和hmtl输出没有似乎告诉我绑定有效。但它只是不，我觉得我错过了一些巨大的东西。JSF＆Primefaces：组件ID不会被发现
验证码：
<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：

无UI：重复一遍，我没有得到任何异常，但没有用户界面：重复一遍，我没有任何内容之一：
<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>
可能的重复http://stackoverflow.com/questions/8634156/how-to-reference-components-in-jsf-ajax-cannot-find-component-with-identifier – perissf
这绝对有可能。这是我之前读过的问题/答案之一。也许我真的不明白，因为它在实践中无法帮助我。 – Lester
