我想使用 Richfaces a4j 支持在页面上异步渲染 6 个块。为此，我定义了 6 个 a4j:region 组件和一个 a4j:commandLink 用于手动刷新组件。

以下是相关代码：

<ui:define name="body">
    <h:form id="dashboardform">
     <div class="table_container" style="width:99%">
        <h:panelGrid id="dashboadPanel" columns="3">

            <a4j:region id="resourceGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box">
                        <ui:include src="dashboard_resourceGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>

            <a4j:region id="profileGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box" >
                         <ui:include src="dashboad_profileGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>

            <a4j:region id="reportGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box" >
                        <ui:include src="dashboard_reportGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>

            <a4j:region id="installedBaseGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box" >
                        <ui:include src="dashboard_installedBaseGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>

            <a4j:region id="simcardGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box">
                        <ui:include src="dashboard_simcardGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>

            <a4j:region id="orderOverviewGraphRegion">
                <h:panelGroup>
                    <div class="rounded_box dashboard_box" id="order">
                        <ui:include src="dashboard_orderOverviewGraph.xhtml"/>
                    </div>
                </h:panelGroup>
            </a4j:region>
        </h:panelGrid>

            <h:panelGrid id="dashboadRefreshPanel" columns="1"  width="100%">
                <a4j:commandButton value="#{I18n.messages['dashboard.btn.refresh']}" 
                    action="#{dashboardBean.doRefresh}" reRender="resourceGraphRegion, profileGraphRegion, reportGraphRegion, installedBaseGraphRegion, simcardGraphRegion, orderOverviewGraphRegion"
                     image="/static/images/refresh.png" style="border:0px; margin-right: 20px; padding: 0px; float: right;" />
            </h:panelGrid>
    </div>

但是，当手动触发 a4j:commandLink 时，整个页面将变为非活动状态（灰显）并出现加载图标。我想要的是页面打开非常顺利，并且所有 6 个区域都呈现异步，因此用户可以获得流畅的体验，而不必等待所有区域完成。

要控制加载通知，您可以使用

<a4j:status id="commonstatus"  startText="In progress..." stopText="Complete"/>

这允许您使用几乎任何“链接”的状态字段来使用该状态控制。
