acegi authorize and commandNavigation2

[Philipp Michel]

Hi list,

i want to use the acegi:authorize tag to hide a commandNavigation2-Tag,
but it doesn't work. It is disappeared all the time, whatever acegi-role
is used.
here the code:

<acegijsf:authorize ifAllGranted="ROLE_APPROVAL">
                        <t:commandNavigation2 value="Statistic Display"
                            action="<backingbean>"
                            activeOnViewIds="/pages/statisticSingle.xhtml">
                         <h:outputText value="hello"/>
                        </t:commandNavigation2>
</acegijsf:authorize>

Anyone knows this issue?

Regards Philipp Michel
