[seam-dev] Seam REST and WELD-001303 No active contexts

Jason,

Thanks for your feedback and maybe this is a regression. I made an interceptor to make my test code work, but I'm not sure what implication it'll have in a production environment.

Ove

@InterceptorBinding
@Target({ TYPE, METHOD })
@Retention(RetentionPolicy.RUNTIME)
public @interface ConversationAware {
}

@ConversationAware 
@Interceptor
public class ConversationHandler implements Serializable {

    private static final long serialVersionUID = -6414852756277060457L;
    
    private BoundConversationContext ctx;
    private BoundRequest request;
    
    private void createBoundConversationRequest() {
        request = new MutableBoundRequest(new HashMap<String, Object>(), new HashMap<String, Object>());
    }

    private void selectBoundConversationContext() {
        ctx = Container.instance().deploymentManager().instance().select(BoundConversationContext.class).get();
        ctx.associate(request);
        ctx.activate();
    }

    private void cleanupBoundConversation() {
        if (ctx != null && ctx.isActive()) {
            ctx.deactivate();
            ctx.dissociate(request);
        }
    }    

    @AroundInvoke
    public Object handle(InvocationContext ctx) throws Exception {
        if (ctx.getMethod().isAnnotationPresent( ConversationAware.class )) {
            createBoundConversationRequest();
            try {
                selectBoundConversationContext();
                return ctx.proceed();
            } finally {
                cleanupBoundConversation();
            }
        }
        return null;
    }    
}

@GET
@Path("/{id:[0-9][0-9]*}")
@Produces(MediaType.APPLICATION_JSON)
@ConversationAware
public Pojo lookupPojoById(@PathParam("id") Long id) {
    // do something
}
