Description

A method marked with @PostLoad or @PostUpdate on an object that is the toMany side of a bi-directional relationship does not get called when the other object is loaded or updated.

I can confirm that this problem was introduced by the changes done in OPENJPA-744. Looks like the StateManagerImpl.postLoad() method is not firing the event due to the bidirectional field not being flagged as loaded.

An example:

@Entity
public class Order {
@OneToMany(cascade = CascadeType.ALL, mappedBy = "order", fetch = FetchType.EAGER)
public List<Shipment> getShipments()

{ return shipments; }

}

@Entity
public class Shipment {
@ManyToOne(fetch = FetchType.EAGER, cascade =

{ CascadeType.MERGE, CascadeType.REFRESH }

)
public Order getOrder()

{ return order; }

@PostLoad
public void doSomethingAfterLoad()

{ // do something }

}

In the above example the doSomethingAfterLoad() never gets called when you load an Order. Without the changes done in OPENJPA-744 it does.
