@TransactionalEventListener is never being called in Spring Framework 4.2

I am implementing @EventListener from Spring 4.2 and it works fine. When I try to implement a @TransactionalEventListener it never gets called.

The ApplicationListenerMethodTransactionalAdapter makes the check:

if(TransactionSynchronizationManager.isSynchronizationActive())

and it is always false so it skips running the event because it says it is not in a transaction.

The code for the event listener is simply:

@TransactionalEventListener()
public void handleTransactionalAddEvent(Event event)
{
    logger.info("Add Event: {}");
}

The code which publishes the event is as follows:

@Override
@Transactional
public Order addToOrder(String username, Long orderId)
{
    Order order = getOrder(orderId, username);

    publisher.publishEvent(new Event(order, Event.EventType.ADD));

    ... Code to do stuff to the order ...

    updateOrder(order);
    return order;
}

If I change the @TransactionEventListener to just be @EventListener, or I add the fallbackExecution attribute it will run fine, but with the @TransactionEventListener it never gets called.

@TransactionalEventListener is used when its method should be within the transaction. If no transaction is running, the listener is not invoked at all since we can’t honor the required semantics.

I found out that we had a custom ApplicationEventMulticaster which was conflicting with the transactional event listeners. I removed it and now it works fine.
