Promoted reference with binding.ws and callback causes null pointer
-------------------------------------------------------------------

                 Key: TUSCANY-1912
                 URL: https://issues.apache.org/jira/browse/TUSCANY-1912
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Axis Binding Extension
    Affects Versions: Java-SCA-1.0
         Environment: All
            Reporter: Simon Laws
             Fix For: Java-SCA-Next


In a binding.ws where client and server are running out of separate composites 
changing the client composite from 
 
   <component name="MyClientComponent">
        <implementation.java class="simplecallback.MyClientImpl" />        

         <reference name="myService">
            <interface.java interface="simplecallback.MyService"
                callbackInterface="simplecallback.MyServiceCallback" />

            <binding.ws 
wsdlElement="http://simplecallback#wsdl.port(MyServiceSoapService/MyServiceSoapPort)
" />
            <callback>
                <binding.ws wsdlElement="
http://simplecallback#wsdl.port(MyServiceCallbackSoapService/MyServiceCallbackSoapPort)"
 />
            </callback>
        </reference>
    </component>

to

    <component name="MyClientComponent">
        <implementation.java class="simplecallback.MyClientImpl" />       
         <reference name="myService"/>
    </component>
   
         <reference name="MyService" promote="MyClientComponent/myService">
            <interface.java interface="simplecallback.MyService"
                callbackInterface="simplecallback.MyServiceCallback" />
            <binding.ws 
wsdlElement="http://simplecallback#wsdl.port(MyServiceSoapService/MyServiceSoapPort)"
 />
            <callback>
                <binding.ws 
wsdlElement="http://simplecallback#wsdl.port(MyServiceCallbackSoapService/MyServiceCallbackSoapPort)
 " />
            </callback>
        </reference> 

I.e, I've turned the component reference into a promoted reference. Causes

java.lang.NullPointerException
