Kaloyan Kolev updated WINK-218:
-------------------------------

          Component/s: Common
          Description: 
I have created a subclass of the AtomEntry, let's say XAtomEntry. When I return that as an entity resource I get exception that there is no provider for that type. The exception is thrown by FlushResultHandler. I tried to wrap the new type in a GenericEntity with a generic type set to AtomEntry, but the result was the same.

Here is the check for the GenericEntity:
{code}
 Class<?> rawType = null;

        if (entity instanceof GenericEntity) {
            GenericEntity<?> genericEntity = (GenericEntity<?>)entity; 
            entity = genericEntity.getEntity(); // this is the XAtomEntity instance
            rawType = genericEntity.getRawType(); // this is the  XAtomEntity class
            genericType = genericEntity.getType(); // this is the AtomEntity class
        } else {
            rawType = (entity != null ? entity.getClass() : null);
            if (isOriginalEntityResponseObj) {
                genericType = rawType;
            } else {
                genericType = (genericType != null ? genericType : rawType);
            }
        }
{code}

This should match the default JAXBXmlProvider, right? 

Later a provider is searched for:
{code}
// get the provider to write the entity
        Providers providers = context.getProviders();
        MessageBodyWriter<Object> messageBodyWriter =
            (MessageBodyWriter<Object>)providers.getMessageBodyWriter(rawType,
                                                                      genericType,
                                                                      declaredAnnotations,
                                                                      responseMediaType);
{code}

Here the messageBodyWriter is set to null.
