[Zope] NameError (global name 'namespace' is not defined)

[Ronald L. Chichester]

Okay, here is a little more diagnostic information.  The 'namespace'
that Zope is complaining about is in the following code:

found    = 0   # flag to indicate that the object was/wasn't found...
contents = []  # the return list...

# Run through the objects in the current (context) folder to see if
there is a match (with given_title)...
for obj in context.objectValues('Image'):
  if found == 0:
    if given_title == obj.title:
      url            = obj.absolute_url
      title          = obj.title    
      contents.append(namespace(url=url, title=title)[0])
      found = 1                  # Set flag on success...

# If you can't find it in the context, then check the container...
for obj in container.objectValues('Image'):
  if found == 0:
    if given_title == obj.title:
      url            = obj.absolute_url
      title          = obj.title    
      contents.append(namespace(url=url, title=title)[0])
      found = 1                  # Set flag on success...

# Return indicative values if the desired object was not found...
if found == 0:
  contents.append(namespace(url='', title='')[0])

vars = namespace(contents=contents)

return vars

As I said before, the above code works just fine in Zope 2-3-1. 
However, it fails (gets the NameError) in both versions 2-4-2 and
2-4-3.  Is this because Zope went to python 2.x instead of 1.5?

Do I have to rewrite my code?  Do I have to tell my client to get 2-3-1? 

Any hints would be greatly appreciated.

Thanks,

Ron
