Invalid WSDL in Delphi 7 Web Services
Since it was missed that the input elements in portType/operation and binding/operation are of different types in the WSDL schema, the TWSDLHTMLPublish object generates an invalid binding/operation/message atribute for every Delphi 7 web service.
Unless it wasn’t properly updated, Report # 15331 was closed without a new build to be generated.
When calling these services, use local tweaked copies of the WSDLs instead.
