[Zope-CMF] using NGFNavigator with CMF

[Maarten Slaets]

Hi,
I'm having problems using NFGNavigator 

http://www.zope.org/Members/gyst/NFGnav

insite a CMF site. In the custom skins directory I've put the following DTML
document, to display the Tree Menu.

----------
<dtml-var "NAVCore.TreeMenu(
	PARENTS,
	REQUEST,
	id(),
	initlevel=1,
	Meta_Types=['Folder','DTML Document','DTML Method','Image','CMF
Site','Document','Portal Folder']
)">
-----------

In the CMF site I've got an 'about' portal folder, and a Document inside tat
(index_html).
when going to that index_html, the tree changes accordingly, BUT when I click
on 'view' or 'edit' I get the following error, which doesn't make any sense
to me when I look at NFG's code:

Does anybody know why it complains about the number of arguments? I did some
testing and it only returns an error when I include 'Document' in the meta
types for NAVCore.TreeMenu()

Thanks
