Events fired from transaction callback are not received

It is not working because you are not providing any implementation for notificationTrigger. See AbstractEventBus.groovy#L128. The afterCommit is correctly triggered but does nothing apart from adding a synchronization.

In the above sample application, it is adding synchronization later in the stage when notify("myEventTag${num}", Instant.now()) is called from the transaction after commit is trigger and notificationTrigger.run() is never executed. I think you can directly call the following instead of registering TransactionSynchronizationAdaptor as:

@Transactional(propagation = Propagation.REQUIRES_NEW)
void doSomething() {
      String random = RandomStringUtils.random(20, true, false)
      log.info('Saving a new SomeDomain: '+ random)
      new SomeDomain(text: random).save()
      notify(Event.from("myEventTag1", Instant.now()), TransactionPhase.AFTER_COMMIT)
}

It works when you call notify in a Promise because TransactionSynchronizationManager.synchronizations.get is null in the new thread and the other branch of notify(Event) method is called here
