对焦时PrimeFaces日历不显示日历

如何解决对焦时PrimeFaces日历不显示日历

使用JSF2.3和PrimeFaces 7.0。当我的页面显示时，它将呈现“文本框”部分，但是当我单击它以将小部件置于焦点时，不会显示日历。 有任何想法吗？我有下面的xhtml。

manualsponsorrpt.xhtml

    <h:head>
        <Meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <h:outputStylesheet name="css/burnsideweb.css" />
        <title>Manual Sponsor Table Report Generator</title>
    </h:head>
    <h:body>
        <f:view>
            <h:form id="manrptForm" rendered="#{menubean.sponsorAdminAuthorized}">
                <h:outputText value="Manual Sponsor Table Report Generator" styleClass="title"/>
                <p:messages showDetail="true" showSummary="true" >
                    <p:autoUpdate />
                </p:messages>
                <h:panelGrid columns="3" styleClass="tableComp" >
                    <p:calendar id="startDate" value="#{sponsorBean.startDate}" />
                    <h:outputText value=" to "/>
                    <p:calendar id="endDate" value="#{sponsorBean.endDate}" />
                    <p:commandButton value="Return to Sponsor Table Admin" action="sponsor"
                                       id="return"/>
                    <h:outputText value="  "/>
                    <p:commandButton value="Generate Report" action="#{sponsorBean.runManualReports}"
                                       id="process" />
                </h:panelGrid>
             </h:form>
            <h1><h:outputText value="You are trying to access one of the LLTS custom apps from outside the Dashboard; this is not permitted. Please log into the dashboard at http://pm.llts.com:9090/LingoApps/faces/menu/menulogon.jsp and access the custom app you want from there."
