This is latest version of fixed kApplication::GetDefaultLanguageId method function GetDefaultLanguageId($init = false) { static $language_info = null; if (!isset($language_info)) { // cache primary language info first $table = $this->getUnitOption('lang', 'TableName'); $id_field = $this->getUnitOption('lang', 'IDField'); $sql = 'SELECT ' . $id_field .
