[news.eclipse.rt.eclipselink] Updating an entity using reflection does n

[Pasi.Kovanen@xxxxxx (Pasi Kovanen)]

I have an entity which looks something like this:

@Entity
public class Entity {
   @Id
   private Long id;
   private String field;

   // Insert getters and setters here...
}

I try to manipulate it using reflection:

Long id = Long.valueOf(1);
Entity entity = em.find(Entity.class, id);

entity.setField("set directly");

Field[] fields = entity.getClass().getDeclaredFields();
for (Field f : fields) {
   if (f.getName().equals("field")) {
       f.setAccessible(true);
       f.set(entity, "set using reflection");
       f.setAccessible(false);
   }
}

System.out.println(entity.getField());

This program prints "set using reflection". However, in the database the 
value set using reflection does not get updated:

SELECT * FROM ENTITY WHERE ID = 1
ID     FIELD
1      set directly

Is it really so that you cannot manipulate entities using reflection? Is 
there a way to overcome this?

I'm using EclipseLink 1.1.1.
