AssertionError: name tns:customValue

[jonblack]

Generating bindings from the following WSDL (http://wiws.cmbi.umcn.nl/wsdl) results in the error:

AssertionError: name tns:customValue

I'm not sure if this is a WSDL problem or a PyXB problem. The WSDL does have xmlns:tns="..." at the beginning.

<wsdl:definitions targetNamespace="http://swift.cmbi.ru.nl/wiws" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://swift.cmbi.ru.nl/wiws" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:sawsdl="http://www.w3.org/ns/sawsdl">

I'm using version 1.2.3 installed via pip.

The full stack trace is:

This is an error in the schema that is part of the wsdl. The problem occurs on line 1729, where a QName is improperly used as the name of an element. The schema correction to apply is:

If you are not already doing so, you can run pyxbwsdl on a locally modified version with:

wget -O cmbi.wsdl  http://wiws.cmbi.umcn.nl/wsdl
# apply fix described above
pyxbwsdl file:cmbi.wsdl
