wall post notification is missing due to oxwall 1.4 update but i figure out where to put the code to make the wall comment works.

Open /ow_system_plugins/base/controllers/comments.php

Find:

$comment = $this->commentService->addComment($params->getEntityType(), $params->getEntityId(), $params->getPluginKey(), OW::getUser()->getId(), $commentText, $attachment);

Add before:


/* ARROWCHAT NEW MESSAGE NOTIFICATION */
$displayName = BOL_UserService::getInstance()->getDisplayName(OW::getUser()->getId());
$sql = "INSERT INTO arrowchat_notifications (to_id, author_id, author_name, type, alert_time)
    VALUES ('".$params->getEntityId()."', '".OW::getUser()->getId()."', '".$displayName."', '3', '".time()."')";
OW::getDbo()->query($sql);
/* END ARROWCHAT MESSAGE NOTIFICATION */

Hope this one helps :)
