6. Implementing Entity Lifecycle via Hibernate Filters forum.hibernate.orgHi Boys, I would like to ask you, how should I correctly implement entity life-cycle using hibernate filters. At this time I have got the following classes and DAOS, which I considered to be right - but they obviously aren't. Here are entities which are used in my system. Code: // AbstractCommontObject ---------------------------------------------- @Entity @FilterDef(name = "softDelete") @Filter(name = "softDelete", condition ... |

8. Using Lifecycle and onDelete to implement logical delete forum.hibernate.orgI'm looking at creating a system where all persistent objects have a cleanupDate field, and to delete an item, you just set the cleanup date to the current date.

11. saveOrUpdate not calling Lifecycle.onUpdate or Lifecycle.onS forum.hibernate.orgGavin, Thanks for responding. I actually have read the Javadoc and was expecting the when session.saveOrUpdate is called that either save or update will be called on the passed entity. But this is not what I am seeing in my application. This is working when I just use save or update though. Thanks, Haytham |
12. Lifecycle: how to get it work? forum.hibernate.orgI actually read both - and found interceptor not really suitable for my needs. I would say that: "Optionally, a persistent class might implement the interface Lifecycle which provides some callbacks that allow the persistent object to perform necessary initialization/cleanup after save or load and before deletion or update." means my persistent class will get the opportunity to do some things ... |

14. Lifecycle objects being sent to an early grave forum.hibernate.orgWhen I have a SQL failure (value to large for column) during a save (or saveOrUpdate), the lifecycle objects are discarded from the Set on the containing object.

15. Tying my domain objects to Lifecycle forum.hibernate.orgIf my domain objects are using the Lifecycle objects extensively, I'm already creating a strong dependency to Hibernate. Now from my Stateless Session Bean facade, should I create a Transfer Object from my Domain Object ?

16. lifecycle - caching/retrieving user object forum.hibernate.orgHi, When I save my business object (e.g. Employee), I stamp the record with a "last_modified_date" value and a "last_modified_user" reference. (which links to the User class of system users). This allows my reports to say Last modified by wglass 5/4/04. Right now, every time my business logic saves the Employee object, it has to update these two fields. It occurs ... |

18. Lifecycle.onUpdate() not called from Session.saveOrUpdate() forum.hibernate.orgI have the problem that Lifecycle.onUpdate() is not called from Session.saveOrUpdate() when the updated object was loaded in the same Session; I didn't notice this before because most of the time I use detached objects. I looked into SessionImpl.saveOrUpdate() and saw that the existence of an EntityEntry causes this behavior. Calling Session.evict() before Session.saveOrUpdate() solved my problem, but it is my ... |

24. Design: session lifecycle in a GUI application forum.hibernate.orgHow do GUI applications typically manage the session lifecycle?

This model fails when multiple instances of the application ... |
25. Session.merge() and Lifecycle forum.hibernate.orgA simple test indicates that the behavior of Session.merge() is inconsistent when a model object implements the Lifecycle interface. The onLoad(), onSave() methods of Lifecycle are invoked at appropriate times during the Session.merge() method, but the onUpdate() method is never invoked. On the other hand, the Session.saveOrUpdate() method invokes onLoad(), onSave() and onUpdate() correctly. I need this function to update the ... |
