<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">Based on <a href="https://issues.jboss.org/browse/CDI-578" title="define behaviour of firing an event for an observer with transaction if the transaction is not open or marked rollback" class="issue-link" data-issue-key="CDI-578" style="color: #3b73af; text-decoration: none">CDI-578</a>.<br /> The spec does not define behavior when you fire an event for an observer with transaction when the transaction itself is not active anymore (or was rolled back).</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">We should determine how to react to such events.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">There are two cases:</p>
<ul>
<li>
Bean Managed Transaction (BMT)
<ul>
<li>
Dirty reproducer can be found <a href="https://github.com/manovotn/core/blob/cdi578/tests-arquillian/src/test/java/org/jboss/weld/tests/event/observer/transactional/TransactionalObserversTest.java#L97" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">here</a>
</li>
<li>
In this scenario no exception was thrown
</li>
<li>
All observers were notified in the following order: <tt>IN_PROGRESS, AFTER_COMPLETION,AFTER_FAILURE, BEFORE_COMPLETION, AFTER_SUCCESS</tt>
</li>
<li>
method <tt>org.jboss.weld.event.TransactionalObserverNotifier.deferNotification(T, EventMetadata, ObserverMethod<? super T>)</tt> was not called at all
</li>
</ul>
</li>
<li>
Container Managed Transaction (CMT)
<ul>
<li>
Dirty reproducer available <a href="https://github.com/manovotn/core/blob/cdi578/tests-arquillian/src/test/java/org/jboss/weld/tests/builtinBeans/ee/EjbBean.java#L59" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">here</a>
</li>
<li>
This throws <tt>WFLYTX0029: Syncs are not allowed to be registered when the tx is in state 1</tt>, where state 1 stand for <tt>STATUS_MARKED_ROLLBACK</tt>
</li>
<li>
The exception is thrown as soon as you attempt to fire the event, so obviously no observers are notified
