Empty ID attributes in responses

           Summary: Empty ID attributes in responses
           Product: Axis
           Version: beta-1
          Platform: PC
               URL: http://www.silbergrau.com
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Basic Architecture
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: pri@silbergrau.com
                CC: pri@silbergrau.com


The following case shows a request and response where 
the response references elements that do not exists. 
Actually the element exist, but it has an empty ID attribute!

Note: This seems to happen whenever AXIS is sending a subclass
of the Type described. In the testcase the method takes a parameter
of TypeA but actual type sent is TypeB.

TYPES: 
------
public class TypeA {
  private TypeA reference;
}

public class TypeB extends TypeA {
}

Remote method = TypeA passThroughTypeA(TypeA a)

REQUEST ENVELOPE: 
-----------------

TypeA a = new TypeA(); 
TypeA b = new TypeB(); 
a.setReference(b); 
b.setReference(null);
