Hi,
Thansk for the report.
I have made a patch which would be in the next release (1.5.1)
You can edit the file "administrator/com_hikaserial/classes/serial.php" and update the delete function.
You just have to add two line just before the end of the function
public function delete($elements) {
//
// Content of the "delete" function.
//
// Update product quantity - Just add these two lines at the end of the function, before the last "return".
$productClass = hikaserial::get('class.product');
$productClass->refreshQuantities();
return $result;
}
With it, the product quantity link would be reprocess (synchronize) each time a serial is deleted.
Regards,
