I want to add context menu with tree. The page is

<rich:tree switchType="client" nodeSelectListener="#{catalogBean.processSelect}"
 reRender="catalog_content_table" ajaxSubmitSelection="true" ajaxSingle="true">
 <rich:recursiveTreeNodesAdaptor roots="#{catalogBean.roots}"
 var="node" nodes="#{node.children}">
 <rich:treeNode>
 <h:outputText value="#{node.name}">
 <rich:componentControl event="oncontextmenu" for="catalog_tree_menu" operation="show">
 </rich:componentControl>
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
</rich:tree>

But the context menu cannot be shown for the leaf nodes. The IE prompts:
Line: 19
Error: 'Richfaces.componntControl' is null or not a object.

I ever tried another methods:

<rich:tree switchType="client" nodeSelectListener="#{catalogBean.processSelect}"
 reRender="catalog_content_table" ajaxSubmitSelection="true" ajaxSingle="true">
 <rich:recursiveTreeNodesAdaptor roots="#{catalogBean.roots}"
 var="node" nodes="#{node.children}">
 <rich:treeNode>
 <h:outputText value="#{node.name}"/>
 <rich:contextMenu attached="true" submitMode="ajax">
 <rich:menuItem ajaxSingle="true" value="Show">
 </rich:menuItem>
 </rich:contextMenu>
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
</rich:tree>

But I got follow errors in IE.

But, if I change the context menu submitMode to 'none', it works.

<rich:tree switchType="client" nodeSelectListener="#{catalogBean.processSelect}"
 reRender="catalog_content_table" ajaxSubmitSelection="true" ajaxSingle="true">
 <rich:recursiveTreeNodesAdaptor roots="#{catalogBean.roots}"
 var="node" nodes="#{node.children}">
 <rich:treeNode>
 <h:outputText value="#{node.name}"/>
 <rich:contextMenu attached="true" submitMode="none">
 <rich:menuItem ajaxSingle="true" value="Show">
 </rich:menuItem>
 </rich:contextMenu>
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
</rich:tree>

However, if the submitMode is 'none', it's not useful.
Who can help me? Thanks.
