[Fedora-suds-list] Server returning correct result as a WebFault

[Matteo Gnudi]

Hello, I'm using SUDS 0.4 and TGWebServices 1.2.4 to expose a webservice
which should return a ComplexType (I'm pretty new to all of this), but
something's not working correctly when this WS is invoked: the output is
what I expected it to be, but I receive it as the message of a WebFault.
Here are the details:

class AuthenticationResponse(object):
    ticket = str
    error = ''
    def __init__(self, error="", ticket=""):
        self.ticket = ticket
        self.error = error

class WebService(WebServicesRoot):

@wsexpose(AuthenticationResponse)
    @wsvalidate(str,str)
    def authentication(self, username='', password=''):
        result = AuthenticationResponse()
        if not (username and password):
            result.error = "Insert both username and password"; return
result
        va = validate_auth(username, encrypt_pw(password)) #Checks if the
credentials are valid
        if va:
            ticket =
base64.urlsafe_b64encode(uuid.uuid4().bytes).replace('=',  '')
            mem[ticket] = dict(expires =
datetime.datetime.now()+datetime.timedelta(hours=1), user = username)
            result.ticket = ticket; return result
        else:
            result.error = "Incorrect username or password"; return result

This is what happens:

client.service.authentication(username='foo', password='bar')

'blahblahblahdiblah', 'error': ''}), {}, <bound method SoapController.index

I was expecting an instance of the AuthenticationResponse object with the
correct parameters being set.

What am I doing wrong? Is this something about SUDS or TGWS?

Thanks in advance for your support.
