Menu Model NavigationPaneRenderer _renderContent

Question

Hello,
I have encountered a hiccup in menu model. JDeveloper 11.1.1.5.
My menu model can work.
Then, I enhanced hide/show based on security setting of resource grant to webpage
and the render of pages is set according to security setting.
However, the item menu under "root menu" does not appear.
The error message i got is:
<NavigationPaneRenderer> <_renderContent> Warning: There are no items to render for this level
//Menu Structure
<?xml version="1.0" encoding="windows-1252" ?>
<menu xmlns="http://myfaces.apache.org/trinidad/menu">
<groupNode id="itemNode_purchasing"
label="Purchasing"
idref="itemNode_purchasing_entry"
rendered="#{securityContext.regionViewable['security.view.pageDefs.purchasingPageDef']}"
visible="#{securityContext.regionViewable['security.view.pageDefs.purchasingPageDef']}">
<itemNode id="itemNode_purchasing_entry" label="Purchasing_entry"
action="adfMenu_purchasing_entry"
focusViewId="/purchasing_entry"
rendered="#{securityContext.regionViewable['security.view.pageDefs.purchasing_entryPageDef']}"
visible="#{securityContext.regionViewable['security.view.pageDefs.purchasing_entryPageDef']}"/>
<itemNode id="itemNode_purchasing_approval"
label="Purchasing_approval"
action="adfMenu_purchasing_approval"
focusViewId="/purchasing_approval"
rendered="#{securityContext.regionViewable['security.view.pageDefs.purchasing_approvalPageDef']}"
visible="#{securityContext.regionViewable['security.view.pageDefs.purchasing_approvalPageDef']}"/>
</groupNode>
</menu>
//Navigation Pane at TemplatePage
<af:navigationPane id="pt_np2" level="1" value="#{site_menu}"
var="menuItem" hint="tabs"
shortDesc="menuItemHere">
<f:facet name="nodeStamp">
<af:commandNavigationItem text="#{menuItem.label}" id="pt_cni2"
action="#{menuItem.doAction}"
rendered="#{menuItem.rendered} "
visible="#{menuItem.visible} "/>
</f:facet>
</af:navigationPane>
Is the something no right or bug?
Appreciate if someone could help.

Hi,
I don't have a testcase, so just guessing
1. Did you check if the root menu item is listed as a page in teh ADF Security editor? Chances may be you don't have permission to access it
2. You use visible and rendered properties, which is not needed. If you choose rendered then the menu item is not rendered if you don't have access privileges. This also means that it cannot be PPR'ed for conditional show/hide. Using visible and set it to false based on the permission will hide the component but keep it as part of the JSF component tree. In your case visible has no effect because you set rendered to true/false
