Example 26 with LifecycleCallbackRegistry

use of org.apache.cayenne.reflect.LifecycleCallbackRegistry in project cayenne by apache.

the class EJBQLQueryIT method testNullObjectsCallback.

@Test
public void testNullObjectsCallback() throws Exception {
    tArtist.insert(1, "a1");
    tArtist.insert(2, "a2");
    tArtist.insert(3, "a3");
    tPainting.insert(1, 2, "title1");
    tPainting.insert(2, 1, "title2");
    tPainting.insert(3, 1, "title3");
    // set callback to be called
    LifecycleCallbackRegistry registry = runtime.getDataDomain().getEntityResolver().getCallbackRegistry();
    registry.addCallback(LifecycleEvent.POST_LOAD, Painting.class, "postAddCallback");
    // select Paintings, where one of it will be null
    EJBQLQuery query = new EJBQLQuery("select a.paintingArray+ from Artist a order by a.artistName");
    List<Painting> result1 = context.performQuery(query);
    assertEquals(4, result1.size());
    assertNull(result1.get(3));
    for (int i = 0; i < 3; i++) {
        assertNotNull(result1.get(i));
        assertTrue(result1.get(i).isPostAdded());
    }
