Perhaps this is intentionally, but...

I have a method with optional parameters and use the autodiscovery-function to generate a wsdl, that I give my SoapServer-Constructor. When I call a method using a soap client (soapui here) and don't specify one of the optional parameters, the call-method of the Soap-Server calls the method using NULL for the optional parameter.

That way, the default values for the optional parameters are not set correctly.

This happens in version 1.10.2. I don't know, if it also happens in earlier versions.
