     * Since these values are stored in separate rows of the i18nStringTable

     * other in prepareRow(). The names of the properties varies, for example,
     * in BoxTranslation they are 'body' and 'title' whereas in
     * MenuLinkTranslation they are 'title' and 'description'. This will save both
