我尝试在树中添加contextMenu来执行自定义操作.该树在overlaypanel内实现.我观察到的是contextMenu只出现在随机情况下,例如在选择和取消选择树上的某些元素之后.任何的想法？

<p:overlayPanel id="advancedSearchPanel" 
    styleClass="ui-advanced-search-overlay"
    for="advancedSearch" 
    hideEffect="fade" 
    my="right top" 
    widgetVar="advancedSearchPanelWidgetVar" > 
        <ui:include src="/search/advancedSearch-form.xhtml"/>  
</p:overlayPanel>

填写AdvancedSearch形式

<p:panelGrid  id="panelAdvanced" styleClass="borderless">
...
    <p:row> 
        <p:column colspan="4"> 
            <p:outputLabel value="#{text['searchForm.classifiers']}" for="treeClassifier" styleClass="paddingLabelGrid"/>

            <p:contextMenu id="contextSearch" for="treeClassifier">
                <p:menuitem value="Escolha todos" update=":searchForm:treeClassifier" actionListener="#{navBarController.displaySelectedSingle}"/>
            </p:contextMenu>

            <p:tree id="treeClassifier" 
                value="#{navBarController.rootClassifier}" 
                var="node" selectionMode="checkbox" 
                selection="#{navBarController.selectedClassifiers}"
                style="height: 200px;width: 540px; margin-bottom: 0px; overflow: auto" 
                propagateSelectionDown="false"
                propagateSelectionUp="false">

                    <p:ajax event="select" update=":searchForm:btnSearch"/> 
                    <p:ajax event="unselect" update=":searchForm:btnSearch"/>     

                    <p:treeNode expandedIcon="ui-icon-folder-open" collapsedIcon="ui-icon-folder-collapsed">
                         <h:outputText value="#{node.description}(#{node.code})"/> 
                    </p:treeNode>  
            </p:tree>
        </p:column>   
    </p:row>
