Class ObsPostLoadEventListener

java.lang.Object

org.openmrs.ObsPostLoadEventListener

All Implemented Interfaces:

Serializable, org.hibernate.event.spi.PostLoadEventListener

@Component
public class ObsPostLoadEventListener
extends Object
implements org.hibernate.event.spi.PostLoadEventListener

Hibernate by default calls setters when initializing a persistent entity from the database meaning an Obs would be marked dirty the first time it's loaded by hibernate, therefore we need to use an instance of this PostLoadEventListener to mark an Obs as not dirty when it gets loaded.

 Note that in hibernate 4, event listeners are now registered via the new integrator and service
 capabilities which leverage Java's standard java.util.ServiceLoader mechanism to discover then
 but unfortunately spring hasn't caught up with these integrator capabilities therefore we need to
 manually 'springfy' the registration of our EventListener
