@DataSet won't trigger the data injection when set on a test super class

[GoogleCodeExporter]

An example is worth an explanation I believe:

Here's my persistence level test super class:

@TransactionConfiguration(defaultRollback = true)
@TestExecutionListeners({ DataSetTestExecutionListener.class })
@ContextConfiguration(locations =
{"file:src/main/webapp/WEB-INF/hibernateContext.xml",
"file:src/main/webapp/WEB-INF/daoContext.xml"})
public class BaseDaoHibernateTest extends
AbstractTransactionalTestNGSpringContextTests {

    /**
     * Empty method that is called before the group of test
     * it triggers the insertion of the DBUnit base data script
     */
    @DataSet(value = "classpath:basedata.xml")
    @BeforeClass(groups = "dao")
    public void setData() {
        logger.warn("Base data are being injected by DBUnit");
    }
}

If I run a test extending this base class, the DBunit data injection won't
be triggered.

public final class CommonDaoHibernateTest extends BaseDaoHibernateTest {

    @Autowired
    private CommonDAOHibernate commonDAOHibernate;

    /**
     * check if the most basic query works out. Verify the Hibernate setup
     */
    @Test(groups = "common")
    public void queryTest() {
        String queryStr = "id = 'admin'";
        List result = commonDAOHibernate.findObject(User.class, queryStr);
        assertNotNull(result);
    }

If I add the @DataSet annotation to the test method, then it works.
My idea is to get a basic set of table populated for the whole suite, then
inject specific Spring Bean based data for each test.

Am I missing something? Or is it because the setData() method in
BaseDaohibernateTest is not a proper test itself?
