ItemUpdated event not firing when list item updated from another event receiver

Question

I have two lists List1 and List2. I have written code to update List2 item from ItemUpdating event of List1. This should fire ItemUpdated event of List2 but it does not. Below is the code I used to update List2 item.

var list = web.Lists["List2"];    
var item = list.GetItemById(Id);

item["City"] = "CityA";
item.Update();

List2 events fires when there is manual update in list but only failing in above case. What am I missing here?

Answer 1

You've stated that you're doing a web.EventFiringEnabled = false in the event receiver for List1.

This will disable event firing across your entire web, including for List2. This explains why your event receiver for List2 is not firing.
