从Backing Bean更新嵌套面板

Question

I have a panel with sections. Each section is separated by a div and has elements in it. I'm trying to update some of the sections from the backing bean based on a poller. The poller calls a bean.

If there is anything to do, the bean should update a table in the first section. In addition, when a row in the table is selected, the bean should update other sections of the panel.

None of the solutions that I have seen show how to update the nested elements.

The problem is that while I can update the whole panel

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

if I try to update anything in the panel
PrimeFaces instance = PrimeFaces.current(); instance.ajax().update("threatForm:threatListPanel:threatListPanelDiv");
it throws a : java.lang.IllegalArgumentException: threatListPanel:

This is the xhtml

<h:form id="threatForm">

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

            </div>
            <!-- End of threatTableColumn1 divider -->

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

            <!-- 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>

This is the update bean

public void updateThreatList() {

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

Is it because I'm updating a div? I tried other elements PrimeFaces instance = PrimeFaces.current(); instance.ajax().update("threatForm:threatListPanel:threatListTable"); PrimeFaces instance = PrimeFaces.current(); instance.ajax().update("threatForm:threatListPanel:threatListTable"); but it didn't seem to make a difference.

Any help/insight would be greatly appreciated. TIA!

I changed the DIV to this:

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

It can't find the component

Answer 1

Fixed it.
It was a combination of two issues. First Is it possible to update non-JSF components (plain HTML) with JSF ajax? I added the jsf:id to the Div

Second from How to find out client ID of component for ajax update/render? Cannot find component with expression "foo" referenced from "bar"

It says to look in the HTML output for actual client ID

Once I had the jsf:id and the actual client ID it all worked
