测试1.xhtml..

我想使用复合组件中的一个面板 id=d 来选择另一个（test2.xhtml）中的下拉值。我是 jsf2.2 的新手，正在努力用自定义组件实现我的逻辑。提前致谢。

<composite:interface>
    <composite:attribute name="AA" required="true" type="java.util.ArrayList" />
    <composite:attribute name="BB" required="true" type="java.lang.Object" />
    <composite:attribute name="CC" required="false" type="java.lang.String" />
    </composite:interface>

    <p:selectOneMenu id="a" value="#{}" >
    </p:selectOneMenu>

    <p:selectOneRadio id="b" plain="true" layout="custom" value="#{cc.attrs.bean.hhhh}">  
    </p:selectOneRadio>


    <p:accordionPanel  id="c">
    <p:outputPanel  id="d > 
    <ui:repeat id="post" value="#{cc.attrs.foo}" var="pooo">
    ---------code---------------------------------
    </p:outputPane>
    </ui:repeat>

    </composite:implementation>

测试2.xhtml

如何在更新所选下拉列表时仅使用 test1.xhtml 中的 id=abc

//With these i can acces all the attributes.It is working fine
    <p:outputPanel id="ZZZZ" >
                <deal:Test1 AA="#{someCode}" BB="someCode" CC="#{}" />
            </p:outputPanel>

// But I want to update only one panel id from test1.xhtml.How to achieve that on selecting a drop down value.

    <p:selectOneMenu id="a" value="#{}">
    <p:ajax listener="#{someMethod}" update="d"/>
    </p:selectOneMenu>
