[Zope] Problems with ZNavigator

[Ralf Kraemer]

i would like to create a new instance of a ZNavigator product folder

in the case of "infobar" is an existing instance from ZNavigator i can use
the following and it works fine

<dtml-with infobar>
      <dtml-call
"manage_addNavigator(id='infobar',title=REQUEST.id,navlink=REQUEST.id,navico
n=navicon,REQUEST=REQUEST)">      
</dtml-with>

but i would like to create a new instance of ZNavigator at a different
place. "/seiten/"

if i try i get the following error code

Error Type: AttributeError
Error Value: manage_addNavigator
