当要阻止的组件通过AJAX更新时,PrimeFaces块UI不起作用

Question

我已经显示了一些组件<p:panel>如下.

<p:growl id="growl" />

<p:panel id="panel" header="New User" style="margin-bottom:10px;">
    <p:messages id="messages" />
    <h:panelGrid columns="3">
        <h:outputLabel for="firstName" value="FirstName: *" />
        <p:inputText id="firstName" required="true" label="FirstName">
            <f:validateLength minimum="2" />
        </p:inputText>
        <p:message for="firstName" />

        <h:outputLabel for="surname" value="Surname: *" />
        <p:inputText id="surname" required="true" label="Surname"/>
        <p:message for="surname" />
    </h:panelGrid>

    <p:commandButton id="saveBtn" value="Save" icon="ui-icon-check" 
                     style="margin:0" 
                     actionListener="#{testManagedBean.insert}" 
                     update="growl panel"/>
</p:panel>

<p:blockUI block="panel" trigger="saveBtn" />

当按下按钮给出,<p:growl>并<p:panel>需要更新其是通过做update="growl panel"的属性<p:commandButton>.<p:panel>在这种情况下,不阻止.

<p:panel>仅在update="growl panel"更改为,update="growl"即跳过面板更新时被阻止.

有办法<p:blockUI>上班吗？<p:panel>应按命令按钮更新.

我已经选择了PrimeFaces Extensions <pe:blockUI>,即使在AJAX更新了要阻止的组件之后也能正常工作,如下所示.

<!--xmlns:pe="http://primefaces.org/ui/extensions"-->

<h:outputStylesheet library="default" name="css/block-ui.css"/>

<pe:blockUI target="panel" 
            content="blockPanelContents" 
            widgetVar="blockUIWidget"/>

<h:panelGrid id="blockPanelContents" columns="2" class="block-contents">
    <h:graphicImage library="default" 
                    name="images/ajax-loader1.gif" 
                    class="block-ui-image"/>

    <h:outputText value="Sending data..." class="block-ui-text"/>
</h:panelGrid>

<p:commandButton id="saveBtn" update="growl panel" 
                 onstart="PF('blockUIWidget').block();" 
                 oncomplete="PF('blockUIWidget').unblock();" 
                 actionListener="#{testManagedBean.insert}" 
                 icon="ui-icon-check" value="Save"/>

使用的CSS类如下所示<h:outputStylesheet>:

.block-ui-image {
    margin-right: 12px; vertical-align: middle;
}

.block-ui-text {
    white-space: nowrap;
}

.block-contents {
    border: none !important;
    padding: 0 !important;
    display:none;
}
