ODE, message's part in SOAP:header

Hi all,
 
It is important for me to embedding a message's part in the soap:header. I designed a simple BPEL process with BPEL Eclipse designer, which receives a "Hello world" and return back. The WSDL output message has two parts defined from element type. The binding protocol is "document" (below). Although it is a simple example, the error is "Message is missing required part: payload1"
 
anyone experience with this, please help!
I'm very appriciate

    <message name="HelloWorldResponseMessage">
        <part name="payload1" element="tns:HelloWorldResponse"/>
        <part name="payload2"
 element="tns:HelloWorldResponse"/>
    </message>
 
    <binding name="HelloWorldSOAPBinding" type="tns:HelloWorld">
     <soap:binding style="document"
      transport="http://schemas.xmlsoap.org/soap/http" />
     <operation name="process">
      <soap:operation soapAction="http://helloworld/process" />
      <input>
       <soap:body use="literal" />
      </input>
      <output>
    <soap:header part="payload1" message="tns:HelloWorldResponseMessage" use="literal"/>
   
    <soap:body parts="payload2" use="literal" />
      </output>
     </operation>
    </binding>
