[Zope-CMF] unable to catch isMemberIdAllowed error

[Alan Runyan]

you should check and then raise an exception
how about:

if REQUEST['username'] in self.acl_users.getUserNames():
    raise 'DuplicateUsername'

and then you can catch 'DuplicateUsername' in your PythonScript
and display appropriate error.
