将方法表达式属性传递给嵌套的复合组件

问题描述

我有复合组件DocumentSelector，其中包含另一个复合组件modalWindow.

I have composite component DocumentSelector, which contains another composite component modalWindow.

<cc:interface componentType="selector.DocumentSelector">
     <cc:attribute name="showSelector"
              method-signature="void listener(java.util.List)"/>
</cc:interface>

<cc:implementation>

    <div id="#{cc.clientId}">
        <ccs:modalWindow id="modal_window" showListener="#{cc.showSelector}"
                     mode="ajax">

        </ccs:modalWindow>
    </div>
</cc:implementation>

我需要将方法#{cc.showSelector}从面组件DocumentSelector传递到复合组件modalWindow.但是我有PropertyNotFoundException因为ElResolver将#{cc}与modalWindow组件而不是DocumentSelector

I need to pass method #{cc.showSelector} to composite component modalWindow from faces component DocumentSelector. But I have PropertyNotFoundExceptionbecause ElResolver associate #{cc} with modalWindow component instead of DocumentSelector

modalWindow组件:

modalWindow component:

<cc:interface componentType="statistics.ModalWindow">
    <cc:attribute name="showListener" method-signature="void show()"/>
    <cc:attribute name="hideListener" method-signature="void hide()"/>
</cc:interface>
<cc:implementation>
</cc:implementation>

我使用Java EE 7，JSF 2.2，WildFly 8.2.0

推荐答案

使用<cc:attribute targets>基本将属性移动到指定的组件，并在必要时使用<cc:attribute targetAttributeName>重命名.

Use <cc:attribute targets> to basically move the attribute to the specified component and use if necessary <cc:attribute targetAttributeName> to rename it.

<cc:attribute ... targets="modal_window" targetAttributeName="showListener" />

别忘了删除showListener="#{cc.showSelector}".
