I use the pull-down-list of Zope to add these objects.

Yes, the product is a ZClass. I imported it into the 'Products' Folder 
inside the 'Control_Panel'.
It seems I have the problem in general. I just imported the ZSiteMap 
product which comes as a .zexp file, but I cannot add the new objects. I 
get the same message:

NameError: global name 'ZSiteMapNode' is not defined (Also, an error 
occurred while attempting to render the standard error message.)

After some restarts of the Zope server it worked temporarely. Do you 
have an idea?
