原则2：不能使LifecycleCallBacks与单表继承实体一起使用？

Question

Is there a bug that doesn't allow this? I've put the LifecycleCallBacks annotation and a prepersist method into the base class (also tried the child classes as well) and can't get LifecycleCallBacks to work. Any input would be greatly appreciated! Thanks!

/**
 * @Entity(repositoryClass="Entity\Repository\EventRepository") 
 * @HasLifecycleCallbacks
 * @Table(name="events")
 * @InheritanceType("SINGLE_TABLE")
 * @DiscriminatorColumn(name="type", type="string")
 * @DiscriminatorMap({"phone" = "PhoneEvent", "meeting" = "MeetingEvent"})
 */
class Event implements \ActivityItem{

    /** @PrePersist */
    public function setComplianceStatus(){...}

}

This didn't work, so I also tried:

/**
 * @Entity @HasLifecycleCallbacks
 */
class PhoneEvent extends Event{

    /** @PrePersist */
    public function setComplianceStatus(){}
}

I tried it with the mapping you proposed and there really seems to be a problem in that constellation.

It worked when I did:

/**
 * ...
 * @Entity
 * @HasLifecycleCallbacks
 */
class Event {
    ...

    /** @PrePersist */
    public abstract function setComplianceStatus();

    ...
}


/**
 * @Entity
 * @HasLifecycleCallbacks
 */
class PhoneEvent extends Event{

    /** @PrePersist */
    public function setComplianceStatus() {
        // implementation goes here
    }
}

As it seems the method has to be present in the parent class, even though it can be declared as abstract. Strange, might be a bug.
