GetCallbackReference return NULL for pomote service

[Dong Liu]

Hi,

It seems the API ComponentContext.getRequestContext().getCallbackReference() 
will not work if the service is pormte to composite service and used by other 
compsite as implementation.composite. Here are the composite files I tried:

innercomposite:
<?xml version="1.0" encoding="UTF-8"?>

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
    targetNamespace="http://inner";  name="InnerComposite">

 <service name="Source" promote="InnerSourceComponent" 
         interface="source.Source" callbackInterface="source.SourceCallback" > 
 </service>
  
 <component name="InnerSourceComponent">
                <implementation.java class="source.SourceImpl"/>   
 </component>
    
</composite>

OuterComposite:
<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
    targetNamespace="http://outer";  xmlns:inner="http://inner";
    name="OuterComposite">
    
    <component name="InnerComponent">
        <implementation.composite name="inner:InnerComposite"/>
        <service name="Source" interface="source.Source"
                 callbackInterface="source.SourceCallback" >
        </service>
    </component>
  
    <component name="RequestComponent">
        <implementation.java class="request.RequestImpl"/>
                <reference name="sourceReference" 
target="InnerComponent/Source" />
     </component> 
        
</composite>

SourceImpl.java:
@Service(Source.class)
@Scope("COMPOSITE")
public class SourceImpl implements Source{

    final static Logger logger = Logger.getLogger(SourceImpl.class);
    private SourceCallback cb;
    private ComponentContext ct; 
    @Context 
    public void setContext(ComponentContext context)
    {
        logger.debug("Set ComponentContext ");
            ct = context;
    }
   
    /*
    @Callback
    public void setSourceCallback(SourceCallback sourceCallback) {
        logger.info("Set callback ");
        cb = sourceCallback;
    }
    */
         
    public void clientMethod(String arg) {
        logger.debug("SOurce clientMehod");
        cb = (SourceCallback) 
ct.getRequestContext().getCallbackReference().getService();
        cb.receiveResult("Callbak response "+ arg);
  }
}


When method clientMethod() is invoked, the getCallbackReference only reutrns 
NULL.

However, the callbackReference is able to be injected by using @Callback 
annotation. 




Would you like to check my composites/java files to help me fimd out where the 
error happens.


Thanks
