Problem in Jdeveloper 10.1.3, web services and document style.possible bug?

Question

Hello!
I would like to generate a document-style web service from a wsdl file. The problem is that when I use it I get the following error:
"operation echoStruct must have exactly one parameter as part of the SOAP body when used with a document-bare binding. All other parameters must be mapped to headers."
A similar message is shown with other wsdl file that I'm using.
I'm attaching the file that use to test it.
Could you help me and tell me how I can fix it, please? or is it a bug?
Regards,
Antonio.

Dev update: WSDL file seems fine. The problem is that it's for a document-bare service and, by default, the Unwrap Wrapped Parameters option on step 2 of the top-down wizard is enabled and checked. This means that we try to pick apart the input message into a series of parameters, yielding the error shown because a document-bare operation must have only one input parameter.
If the Unwrap Wrapped Parameters option is unchecked, creation of the top-down service will succeed. In future, we ought to disable the option completely for everything but document-wrapped services, as that's the only time it applies.
This is covered by bug 4630382.
