Question

给定以下实现，在composite中设置正确的值是什么：actionSource @ name或@targers，以便我的actionSource引用a4j：commandButton @ id =“yes”

<composite:implementation>
    <a4j:commandButton value="Delete selected" execute="@this"
                       oncomplete="#{rich:component('confirmDeletePopup')}.show()"/>
    <rich:popupPanel id="confirmDeletePopup">
        <h:form id="confirmForm">
            <a4j:outputPanel id="confirmDeletePanel" styleClass="popup">
                <h:panelGroup rendered="#{not empty cc.attrs.deleteSelectedBean.selection}">
                    Are you sure?

                    <div class="popupButtons">
                        <a4j:commandButton value="Yes" id="yes"
                                           execute="@this" 
                                           action="#{cc.attrs.deleteSelectedBean.deleteSelected()}"
                                           oncomplete="#{rich:component('confirmDeletePopup')}.hide(); return false"/>
                        <h:commandButton styleClass="yesNo"
                                         value="No" immediate="true">
                            <rich:componentControl target="confirmDeletePopup" operation="hide" />
                        </h:commandButton>
                    </div>
                </h:panelGroup>

                <h:panelGroup rendered="#{empty cc.attrs.deleteSelectedBean.selection}">
                    First choose what you want to delete!
                    <div class="popupButtons">
                        <h:commandButton value="Cancel" immediate="true">
                            <rich:componentControl target="confirmDeletePopup" operation="hide" />
                        </h:commandButton>
                    </div>
                </h:panelGroup>
            </a4j:outputPanel>
        </h:form>
    </rich:popupPanel>
</composite:implementation>

编辑：截至目前，我尝试了name =“yes”：

<composite:interface>
    <composite:attribute name="deleteSelectedBean" type="pl.aw.presentation.common.DeleteSelectedEntitiesBean"/>
    <composite:attribute name="render" />
    <composite:actionSource name="yes"/>
</composite:interface>

尝试按如下方式引用actionSource：

听众如下：

public class OrganizationListBean {
    //...
    public ActionListener getDeleteListener() {
        return new ActionListener() {
            @Override
            void processAction(ActionEvent event) throws AbortProcessingException {
                System.out.println("listener run");
            }
        }
    }
}

但代码未执行。

我也尝试过添加（由Intellij Idea自动完成提议）targets="confirmDeletePopup:confirmForm:confirmDeletePanel:yes"但是我得到了

java.lang.IllegalArgumentException: confirmDeletePopup
        at javax.faces.component.UIComponentBase.findComponent(UIComponentBase.java:612) [jboss-jsf-api_2.1_spec-2.1.18.Final.jar:2.1.18.Final]
        at com.sun.faces.facelets.tag.composite.AttachedObjectTargetImpl.getTargets(AttachedObjectTargetImpl.java:96) [jsf-impl-2.1.29-03.jar:2.1.29-03]

我使用JBoss EAP 6.1.Alpha和Mojarra升级到jsf-impl-2.1.29-03。

documentation似乎很清楚：

targets - 按钮的ID（
name - 如果您未设置targets，则按钮的ID，否则它只是一个标识符

所以你设置name =“yes”。

嵌套组件的有效actionSource名称/目标
