Default Void and Cancel Void do not trigger total ticket changed but Cancel does.
I set up Ticket Total Change Rule with Show Message action "Total Changed: message.
Edit: I also notice Total Ticket Changed trigger 2 times when order added and before select portion (using ask question with portion button) even no change in total and one more after select portion which total has changed.
@emre this issue will effect this %10 service charge for selected products tutorial as well.
In some cases we forcibly execute it. That might be the reason of it. If it leads to an issue adding a constraint check to test previous and actual totals will solve that.
