从Backing Bean更新嵌套面板

Question

    PrimeFaces instance = PrimeFaces.current();
    instance.ajax().update("threatForm:threatListPanel");

如果我尝试更新面板中的任何内容
primeFacesinstance=PrimeFaces.current（）；instance.ajax（）.update（“ThreatForm：ThreatListPanel：ThreatListPanelDiv”）；
它抛出：java.lang.IllegalArgumentException：ThreatListPanel：

这是xhtml

<h:form id="threatForm">

    <!-- Update the threat list at regular intervals -->
    <p:poll interval="#{threatMonitorView.pollInterval}"  listener="#{threatMonitorView.updateThreatList()}" />

    <p:panel id="threatListPanel" header="Threat Monitor Page">
        <div id="threatListPanelDiv" class="threatPanel">
            <!-- column with threats listed -->
            <div class="threatTableColumn1">
                <p:column>
                    <p:dataTable id="threatListTable" var="singleThreat"
                        widgetVar="threatTable" value="#{threatMonitorView.threats}"
                        selectionMode="single"
                        selection="#{threatMonitorView.selectedThreat}"
                        rowKey="#{singleThreat.uniqueId}" scrollable="false"
                        sortBy="#{singleThreat.timeReceived}">

                        <!-- update the information area when a threat is selected -->
                        <p:ajax event="rowSelect"
                            listener="#{threatMonitorView.onRowSelectThreat}" />

                        <p:column headerText="Active Threats">
                            <!-- header stuff -->

                        </p:column>
                    </p:dataTable>
                </p:column>
                <!-- end of column 1 -->
            </div>
            <!-- End of threatTableColumn1 divider -->

            <!-- Threat info -->
            <div class="threatTableColumn2">
                <p:column id="threatTableColumn2Id">

                    Stuff in this colunm


                </p:column>
                <!-- column 2 end -->
            </div>
            <!-- End of threatTableColumn2 divider -->

            <div id="threatTableColumn3Div" class="threatTableColumn3">
                <p:column>

                    Stuff in this column

                </p:column>

            </div>
            <!-- End of threatTableColumn3 -->

            <div class="threatTableFooter">
                <p:commandButton value="Close" id="threatCloseButton"
                    action="#{threatMonitorView.closeThreatButton()}"
                </p:commandButton>
            </div>
            <!-- End of threatTableFooter divider -->
        </div>
        <!-- end of threatPanel -->
    </p:panel>

</h:form>

这是更新bean

public void updateThreatList() {

    if (tlm.isThreatListChanged()){
        PrimeFaces instance = PrimeFaces.current();
        instance.ajax().update("threatForm:threatListPanel:threatListPanelDiv");
        tlm.setThreatListChanged(false);
    }
}

<div jsf:id="threatListPanelDiv" class="threatPanel">

Answer 1

修正了它。
这是两个问题的组合。首先，是否可以用JSF Ajax更新非JSF组件（纯HTML）？我将jsf：id添加到Div

其次，如何找出ajax更新/呈现组件的客户端ID？找不到从“bar”引用表达式“foo”的组件

它表示在HTML输出中查找实际的客户端ID
