[Brian Leathem (JIRA)]

     [ https://issues.jboss.org/browse/RF-11915?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Leathem updated RF-11915:
-------------------------------

           Description: 
Submenu (r:menuGroup) containing only disabled items or no items, causes a JavaScript error when it is supposed to get hidden (moving cursor to the next item in the parent menu).

In Firefox 9:
{quote}
parentMenu is undefined
menu-base.js, line 126
{quote}

In MSIE 7:
{quote}
'nodeType' is null or not an object
richfaces.js, line 43
{quote}

It's the same error only reported from the different level of the call stack.

It's the same error only reported from the different level of the call stack.

    Steps to Reproduce: 
Test case {also works with "Disabled item" removed):

{code}
<rich:toolbar layout="hbr">
    <rich:dropDownMenu label="Menu test case">
        <rich:menuItem label="First item" />
        <rich:menuGroup label="Submenu with disabled items">
             <rich:menuItem label="Disabled item" disabled="true" />
        </rich:menuGroup>
        <rich:menuItem label="Last item" />
    </rich:dropDownMenu>
</rich:toolbar>
{code}

# open the menu "Menu test case"
# move the cursor down by the items
# after leaving "Submenu with disabled items" and moving to "Last item", the error appears.
