Hooks not working. #37

Closed yngbldjr closed 10 years ago

yngbldjr commented 10 years ago

I can not get ComponentHook - specifically EventBusHook working since .7.

I see the fields getting set from the handleStart, but when the other methods are called, the fields are null. Here is a small snippet. I added the EventBusHook to the NetworkTest integration test.

java.lang.NullPointerException at net.kuujo.vertigo.hook.EventBusHook.handleSend(EventBusHook.java:52) at net.kuujo.vertigo.io.port.impl.DefaultOutputPort.triggerSend(DefaultOutputPort.java:382) at net.kuujo.vertigo.io.port.impl.DefaultOutputPort.send(DefaultOutputPort.java:400) at net.kuujo.vertigo.io.port.impl.DefaultOutputPort.send(DefaultOutputPort.java:53) at net.kuujo.vertigo.test.integration.NetworkTest$TestManyToOneSender.start(NetworkTest.java:197) at org.vertx.java.platform.Verticle.start(Verticle.java:82)

Alright so the problem is with serialization. Vertigo 0.7 configurations are constantly changing as Vertigo synchronizes with other nodes in the cluster. The problem is that the component hook and IO hooks actually end up being two separate instances of the same class. The component hook is properly started, but handleStart is never called on the IO hook. I'm doing a little refactoring to make sure the same instance is used in the component and inputs and outputs.
