Python-zeep: 'Sequence' object has no attribute '_require_keyword_arg'

[dddtc2005]

Hello! Continued my development and found another issue for the "Set" operation in the same wsdl I provided.

Code as following:

motype = 'EPSMultiSC@http://schemas.example.com/ma/HSS/'
moid = {'imsi': imsi}
moattr = {'SetEPSMultiSC': {'epsOdb': 'ODB-ALL'}}
mesg = soapclient.service._binding.create_message('Set', motype, moid, moattr, _soapheader=sessionid)
response = soapclient.service.Set(motype, moid, moattr, _soapheader = sessionid)

Error gives out:

Traceback (most recent call last):

The wsdl and xsd are the same as in issue 74

Hi!

Tried again with the modification, but got following errors:

Ok, sorry for this again. Seems you are using a wsdl which resolves around xsd items which aren't tested that good yet. I'll dive into this later

[dddtc2005]

Hello! Any updates on this? Or shall I open a new one for better tracking? Thanks!

[mvantellingen]

Completely forgot about it :), re-openend

[mvantellingen]

Small update: The issue is caused by a double nested sequence element (.. in the xsd). This is actually allowed and I' currently refactoring a lot of stuff to support this but in the meantime if you can edit the xsd's and remove the in this case unnecessary double nesting then it should work for now.

[mvantellingen]

hi @dddtc2005, I've just finished the refactoring of the xsd processing to handle this case. Can you test #101 for me? It still needs some minor cleanup, docstrins etc before I merge it to master. But I appreciate it if you could let me know if the PR solves your issue

[dddtc2005]

Sure, I will have a try and let you know later

[mvantellingen]

FYI; I just merged that branch to master, so if you could give the master branch a try that would be great 👍

[mvantellingen]

I'll close it for now, let me know if you still have issues.
