Children objects are deleted from the datastore but still appear in the Data Viewer

[GoogleCodeExporter]

Children objects of a one-to-one unidirectional relationship are deleted
from the datastore when its parent is deleted but they still show in the
Data Viewer.

The getObjectById() methods throw correctly the JDOObjectNotFoundException
but the DayCallsStat object still appear in the Data Viewer.

Here's the snippet reproducing the problem:
----------------
        PersistenceManager pm = PMF.get().getPersistenceManager();

        String userId = "0";
        Key userKey = KeyFactory.createKey(User.class.getSimpleName(), userId);
        String userEncodedKey = KeyFactory.keyToString(userKey);
        String dayCallsStatEncodedKey = KeyFactory.createKeyString(userKey,
DayCallsStat.class.getSimpleName(), userId);
        User user = null;
        Transaction tx = pm.currentTransaction();
        try {
            for(int tries=0; tries < 4; tries++) {
                tx.begin();
                try {
                    try {
                        user = pm.getObjectById(User.class, userEncodedKey);
                        tx.commit();
                        break;
                    } catch(JDOObjectNotFoundException e) {
                        user = new User();
                        user.setUserId(userId);
                        user.setEncodedKey(userEncodedKey);

                        long now = System.currentTimeMillis();
                        DayCallsStat dayCallsStat = new DayCallsStat();

dayCallsStat.setStartOfPeriodCallsTimestamp(Utils.getStartOfDayTimestamp(now));

dayCallsStat.setEndOfPeriodCallsTimestamp(Utils.getEndOfDayTimestamp(now));
                        dayCallsStat.setUserId(userId);
                        dayCallsStat.setEncodedKey(dayCallsStatEncodedKey);
                        user.setDayCallsStat(dayCallsStat);
                        pm.makePersistent(user);
                        tx.commit();
                        logger.info("User created. User: " + userId);
                        break;
                    }
                } catch (JDOException r) {

sadly the "snippet" doesnt define the classes involved, so not reproduceable 
and downgraded to low priority. Obviously looking at the log would tell you more
