[Soap-Python] Spyne: problems getting complex nested return value definition right

[Jussi Rasinmäki]

Hi,

I've got the following test setup defined:

###############################################################################
# TestResponse
###############################################################################

class InvalidValue(ComplexModel):
    __namespace__ = 'http://xml.test.org/TestResponse/2012/07/13'

    Attr = String
    Value = Double

class InvalidValues(ComplexModel):
    __namespace__ = 'http://xml.test.org/TestResponse/2012/07/13'

    InvalidValue = InvalidValue.customize(min_occurs='1',
                                          max_occurs='unbounded')

class FailedValidation(ComplexModel):
    __namespace__ = 'http://xml.test.org/TestResponse/2012/07/13'

    id = XmlAttribute(String)

    InvalidValues = InvalidValues
    Rule = String


class TestResponse(ComplexModel):
    __namespace__ = 'http://xml.test.org/TestResponse/2012/07/13'

    TaskId = XmlAttribute(String)

    FailedValidation = FailedValidation.customize(max_occurs='unbounded')


###############################################################################
# Service classes
###############################################################################

class TestService(ServiceBase):

    @rpc(String, _returns=TestResponse)
    def TestService(data):
        iv1 = InvalidValue(Attr='Basal area', Value=100.)
        ivs1 = [iv1]
        f1 = FailedValidation(id='10', Rule='Some validation rule',
                              InvalidValues=ivs1)
        iv2 = InvalidValue(Attr='Basal area', Value=100.)
        ivs2 = [iv2]
        f2 = FailedValidation(id='11', Rule='Some other validation rule',
                              InvalidValues=ivs2)
        fv = [f1, f2]
        res = TestResponse(TaskId='1', FailedValidation=fv)
        from celery.contrib import rdb;rdb.set_trace()
        return res

application = Application([TestService],
                          'http://ws.test.org/testws/',
                          interface=Wsdl11(),
                          in_protocol=Soap11(),
                          out_protocol=Soap11())

Running it, and dropping to the remote debugger yields:

(Pdb++) res
TestResponse(FailedValidation=[FailedValidation(InvalidValues=[InvalidValue(Attr='Basal
area', Value=100.0)], Rule='Some validation rule', id='10'),
FailedValidation(InvalidValues=[InvalidValue(Attr='Basal area',
Value=100.0)], Rule='Some other validation rule', id='11')],
TaskId='1')

But the returned xml is:
  <senv:Body>
    <tns:TestServiceResponse>
      <tns:TestServiceResult TaskId="1">
        <s0:FailedValidation id="10">
          <s0:InvalidValues>
            <s0:InvalidValue/>
            <s0:InvalidValue/>
          </s0:InvalidValues>
          <s0:Rule>Some validation rule</s0:Rule>
        </s0:FailedValidation>
        <s0:FailedValidation id="11">
          <s0:InvalidValues>
            <s0:InvalidValue/>
            <s0:InvalidValue/>
          </s0:InvalidValues>
          <s0:Rule>Some other validation rule</s0:Rule>
        </s0:FailedValidation>
      </tns:TestServiceResult>
    </tns:TestServiceResponse>
  </senv:Body>

I.e., no content in the InvalidValue elements although the Python
objects were there.

Doing something wrong here obviously, but what?

Kind regards,
Jussi
