The best suggestion I would have is to create a CXF client from the WSDL and try that. Capture the SOAP message from it and then also capture the message from the Delphi client and compare them.
USUALLY, a null param is the result of the client doing the namespaces wrong. For example, your schema has: elementFormDefault="unqualified" if the SOAP message has something like: <foo xmlns="http://....."> to set the default namespace, that will cause an issue.
