Logic hooks not working on new records

[cumanacr]

Issue

Logic hooks checking new records using:

if (!isset(self::$fetchedRow[$bean->id])) {

Are no longer working, it seems something changed on base SuiteCRM

Expected Behavior

Logic hook not firing on new records, it seems that is working properly on existing records somehow

Actual Behavior

Only existing records code is firing on the logic hooks

Possible Fix

Change isset for empty check
