The `self` in self.generateUniqueId is the KC basefolder.  So it seems
this folder does not have that method.  Maybe in your tests you are
invoking that method on a DownloadedDocument?

If this does not help you, you could try going in with the python
debugger.  Add a line

  import pdb; pdb.set_trace()

just before the line calling self.generateUniqueId and examine the
situation there or step into (press 's') that method call and see why
it fails.


Maybe of use is an example of a generateUniqueId method, in a content
type of eXtremeManagement:
