When I insert a link, connector tries to insert the link in wrong table (task table)

Hello Everybody, I installed succesfully gantt and configured connector.
On the client side I have:

gantt.init(“gantt_here”);
gantt.load("preventivi/connector.php?preventivo=1);
var dp = new gantt.dataProcessor("preventivi/connector.php?preventivo=1);
dp.init(gantt);

And the cnnector.php file is:

<?php require_once("db_config.php"); require_once("../../assets/plugins/dhtmlx_gantt/connector/gantt_connector.php"); function my_update($data) { $data->add_field("preventivo",$_GET['preventivo']); } $res = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME, DB_USER, DB_PASS); $dbtype = "PDO"; $gantt = new JSONGanttConnector($res, $dbtype); $gantt->enable_log('/home/site/public_html/downloads/log.txt',true); if($gantt->is_select_mode()) { $gantt->mix("open", 1); $gantt->filter("preventivo", $_GET['preventivo']); $gantt->render_links("gantt_links_preventivi", "id", "source, target, type, preventivo"); $gantt->render_table("gantt_tasks_preventivi", "id", "start_date, duration, text, progress, parent, color, textColor, preventivo"); } else { $gantt->event->attach("beforeInsert", "my_update"); $gantt->render_links("gantt_links_preventivi", "id", "source, target, type"); $gantt->render_table("gantt_tasks_preventivi", "id", "start_date, duration, text, progress, parent, color, textColor"); } ?>

All works well but when I try to insert a link I notice a very strange behaviour: connector tries to insert the link not in gantt_links_preventivi table but in gantt_tasks_preventivi as shown in log file:

What happens? I’ve tried everything but I couldn’t figure out where the problem is!
has anyone had this problem?
Thanks

Hello,
Thank you for reporting about the issue. I was able to reproduce it. Looks like, it happens only in the latest version (6.1.1). I told the dev team about it, they will include the fix in the 6.1.2 version. Please, wait until it is released. If you have the Pro/Trial version, you can contact the support team and mention this topic, and we’ll send you the newer version.
