I am trying to add an event receiver on the workflow task - list Item Added event, to get the Task ID and update it on another SharePoint List.

This is because once I add an Assign Flexi Task action on the Nintex workflow, there is no way to get the created task ID in the workflow, unless someone actions on the task.

However, the Event Receiver on the Workflow Task list Item Added event does not fire!?

Can someone help me in solving this? or any alternative solution please.enter image description here

There is a good chance that one of these is true:

  1. New solution was not deployed correctly.
  2. The event receive is not registered correctly.
  3. You din't restart app pool or IIS.
  4. Nintext blocks event receivers when creating a task.

The first step is to conirm that you have event receiver registered. To do it:

  • Click Find current web
  • Locate EventReceivers for your list/library

  • Verify that A) Event receiver exinsts and B) It has correct Synchronization type

The issue has been solved by Restarting the IIS and restarting the SharePoint Timer Process.
