This issue is to remove a feature that is only partly implemented in the JDO objectstore, namely the lifecycle methods.
Jeroen and I were discussing this, and think they are possibly an anti-pattern since they tend to lead to fragile code.
Rather than have the object "pushing" changes to others, it would be better if an event were broadcast via the EventBus. That way a subscribing service could pull appropriate changes and do whatever is necessary.
domainEventOnLoad = ...,
domainEventOnSave = ...,
domainEventOnUpdate = ...,
domainEventOnDelete = ...,
By using the corresponding associated phases, ie EXECUTING and EXECUTED, the subscriber can act BEFORE and/or AFTER the domain object is loaded / initially saved-persisted / updated / deleted.
The "domainEventOnLoad" event would allow the user to "veto" a specific domain entity instance (domain object) to be showed due to security or other business reasons.
