>    Affects Versions: Java-SCA-1.0
>            Reporter: Mark Combellack

> If you call the getCallback() method on the RequestContext for a Component that does not have a call back, the code throws a NullPointerException:
> java.lang.NullPointerException
>   at org.apache.tuscany.sca.core.context.RequestContextImpl.getCallback(RequestContextImpl.java:77)
>   at net.ubiquity.sipsoa.compliance.requestcontext.basic.RequestContextPojoImpl.testGetCallback(RequestContextPojoImpl.java:95) 
>   .....
> This is different behaviour to the RequestContext.getCallbackReference() method that will just return null.
