using xmlbeans on client side (in conjunction with axis2); null returns although data is available

Hello together,

i have a problem with using xmlbeans.
Following situation is given.

- remote wsdl available (see http://pastebin.com/5qnFScMx)
- code generation using axis2 and databinding xmlbeans

i can do a request and i get a response, too.

The problem is while iterating through given response.
I just want to get part of the response with xmlbeans therefore i post
the question on this mailing list.

this is toString-ouput of the response:

(1)

Following code snippet i use:
fully object "GetImageURLResponseDocument response" is given  (see 1)
GetImageURLResponse imageResponse = response.getGetImageURLResponse();  (see 2)
Order order = imageResponse.getReturn();  <==  null returns

method body of "getReturn" is :
        public com.fm_ged.neopod.ria.recettage.ws.Order getReturn()
        {
            synchronized (monitor())
            {
                check_orphaned();
                com.fm_ged.neopod.ria.recettage.ws.Order target = null;
                target =
(com.fm_ged.neopod.ria.recettage.ws.Order)get_store().find_element_user(RETURN$0,
0);   <= nothing is found therefore null
                if (target == null)
                {
                    return null;
                }
                return target;
            }
        }

The variable "RETURN$0" is:
        private static final javax.xml.namespace.QName RETURN$0 = new
javax.xml.namespace.QName("", "return");

i use
Axis 1.6.0
xmlbeans-2.3.0.jar

What is going wrong?
Is the server response maybe wrong?
Something wrong on my client side?

Any help is appreciated!

Thanks in advance!
