Jim checked in a change this morning that should fix this.

Michel,
I did a CVS update at 9 am or so PST and whe I changes the meta-type
inside the ZClass, it still doesn't change in the add list, or t he
SubObjects list. Do I need to give it another go?
I'll look into this:
...
Also, I was wondering if you got my last mail about the Catalog not
indexing the objects (Or adding them to the catalog at all) 
unless I use
the "Find Items to Catalog" tab.  I have tried the DTML route, but you
had said that would not be as efficient so (and it did work 
:).  I'm now
using an external method called index_object, drawn verbatim from the
mail you sent.
def index_object
    try: self.Catalog.catalog_object(self,self.url())
    except: pass
Ah I neglected to mention that your Findable class needs to define the
url method. ;)  It should be an external method, just like index_object:

def url(self, ftype=urllib.splittype, fhost=urllib.splithost):
    """Return a SCRIPT_NAME-based url for an object."""
    if hasattr(self, 'DestinationURL') and \
       callable(self.DestinationURL):
        url='%s/%s' % (self.DestinationURL(), self.id)
    else: url=self.absolute_url()
    type, uri=ftype(url)
    host, uri=fhost(uri)
    script_name=self.REQUEST['SCRIPT_NAME']
    __traceback_info__=(`uri`, `script_name`)
    if script_name:
        uri=filter(None, string.split(uri, script_name))[0]
    uri=uri or '/'
    if uri[0]=='/': uri=uri[1:]
    return uri
...
I use that external method in the add constructor of the ZClass,
<!--#with "EmployeeClass.createInObjectManager(REQUEST['id'], 
REQUEST)"-->
<!--#call "propertysheets.properties.manage_changeProperties(
                  name=REQUEST['name'],
             wagner_name=REQUEST['wagner_name'],
        	  extension=REQUEST['extension'],
        	  address=REQUEST['address']
        	  )"-->
<!--#call index_object-->
<!--#/with-->
It creates the object, but does not add it to the catalog.  
Is this a bug?
All my best,
