Description

Noticed that POST_LOAD is not invoked when an object was prefetched with another object. Here is a test case:

+ public void testPostLoad_Prefetch() throws Exception

{ + LifecycleCallbackRegistry registry = getDomain() + .getEntityResolver() + .getCallbackRegistry(); + + ObjectContext context = createDataContext(); + + registry.addListener(LifecycleEvent.POST_LOAD, Artist.class, "postLoadCallback"); + MockCallingBackListener listener = new MockCallingBackListener(); + registry.addListener( + LifecycleEvent.POST_LOAD, + Artist.class, + listener, + "publicCallback"); + + Artist a1 = context.newObject(Artist.class); + a1.setArtistName("XX"); + Painting p1 = context.newObject(Painting.class); + p1.setToArtist(a1); + p1.setPaintingTitle("XXX"); + context.commitChanges(); + + // reset context and read related object + context = createDataContext(); + + SelectQuery q = new SelectQuery(Painting.class); + q.addPrefetch(Painting.TO_ARTIST_PROPERTY); + p1 = (Painting) context.performQuery(q).get(0); + + // artist is prefetched here, and a callback must have been invoked + a1 = p1.getToArtist(); + assertEquals(PersistenceState.COMMITTED, a1.getPersistenceState()); + assertEquals(1, a1.getPostLoaded()); + assertSame(a1, listener.getPublicCalledbackEntity()); + }
