I *think* I've created a getUserNames python method that returns the
appropriate results:
Parameter list:
self
Body:
user_ids=self.UserSource.getPersistentItemIDs()
names=[]
 for i in user_ids:
     names.append(self.getItem(i))
 return names
Returns a list of objects.
...
I don't understand the differences between the code I pasted above and
the code on the original getUserNames method (from :
def getUserNames(self):
        """Return a list of usernames"""
        names=self.data.keys()
        names.sort()
        return names
Returns a list of usernames.
...
Can anyone tell me what I need to fix?
Unfortunately, I cannot yet.
Does anyone on the list know how to change the getUserNames
Python method to return a list of names instead of a list of
objects?

The code in question is this:

  user_ids=self.UserSource.getPersistentItemIDs()

  names=[]
  for i in user_ids:
      names.append(self.getItem(i))
  return names

Thanks,
