Subject Re: What might cause "Unexpected subelement return"?
Date Tue, 25 Mar 2008 01:25:42 GMT
When you modify the WSDL, specify type="ns0:Person" in place of the
type="xs:anyType".
(See the recommended fix in my last response)

 For this I modified the calculator example.  I instead of performing a calculation, my service
now requires an integer.  In response to this integer the service creates the specified number
of Person instances, each of which have one Address.
