[Nepomuk] notes deleted by Nepomuk

[PierreL]

HI,

Our application creates a new note by doing the following below. Why does Nepomuk issue "delete from ..." as soon as our appl start? In <= 4.3.5 using sesame2 as backend this never happened with the same code.

----------------------------------------------------------------------

void MainWindow::newNote()
{
    QString uri = Nepomuk::ResourceManager::instance()->generateUniqueUri();
    Note n = Note(uri);

    m_model->insertRows(0, 1);
    m_model->setData(m_model->index(0, 0, QModelIndex()), uri, Qt::EditRole);
    ui->view->setCurrentIndex(m_proxyModel->mapFromSource(m_model->index(0, 0, QModelIndex())));
}


Note::Note(const QString &uriOrName)
    : Nepomuk::Thing(uriOrName, Nepomuk::Vocabulary::PIMO::Note())
{
    if (!isValid()) {
        QDateTime now = QDateTime::currentDateTime().toTimeSpec(Qt::LocalTime);
        setCreated(now);
        setLastModified(now);
    }
}


void Note::setCreated(QDateTime newCreated)
{
//    qDebug("%s", qPrintable(newCreated.toString())); //FIXME: if i delete this it sets date time to 0. Why?
    setProperty(Soprano::Vocabulary::NAO::created(), Nepomuk::Variant(newCreated));
}

/**
 * Sets the time and date of the last write access to the note (by setting the \c lastModified property of the note in the RDF Repository).
 */
void Note::setLastModified(QDateTime newModified)
{
    setProperty(Soprano::Vocabulary::NAO::lastModified(), Nepomuk::Variant(newModified));
}
