Hi all.
I want to get notified when a domain object is going to be removed.
I have defined it as this:
public class Relationship {
…
public void removing() {
this.eventBusService.post(new RelationshipRemovingEvent(this));
}
...
}
And an Event Handler like this:
public class RelationshipsBCMInformationEventHandler extends AbstractXMSService
{
// {{ RELATIONSHIPS EVENTS HANDLER
@Subscribe
@Programmatic
public void on(final RelationshipRemovingEvent event) {
try {
final RelationshipBCMInformation relationshipBCMInformation =
this.wrap(this.relationshipsBCMInformation).businessContinuityInformation(event.getRelationship());
this.getContainer().remove(relationshipBCMInformation);
this.getContainer().flush();
} catch (final Exception e) {
e.printStackTrace();
throw new ApplicationException(e);
}
}
// }}
// {{ injected: RelationshipsBCMInformation
@Inject
private RelationshipsBCMInformation relationshipsBCMInformation;
// }}
// {{ injected: EventBusService
@Programmatic
@PostConstruct
public void postConstruct() {
this.eventBusService.register(this);
}
@Programmatic
@PreDestroy
public void preDestroy() {
this.eventBusService.unregister(this);
}
@javax.inject.Inject
private EventBusService eventBusService;
// }}
}
Problem is that when the code enters the “on” event handler, the reference to
the relationship accessed on "event.getRelationship()” is already marked as
deleted:

So, as it could be a quite “common” events-related use case (referencing the
same entity “before” deleting it), could the event be dispatched BEFORE sending
the object to DN to mark it as deleted?
Or, is there any other way to detect when an object is going to be deleted
(previously to being deleted, obviously) ?
Thanks in advance,
Oscar
