Trigger now firing when i am controlling recusiveness

Question

I am trying to populate Notes_Preview__c on Description for event.

However it is not populating.

trigger:

if(trigger.isAfter ){

if(trigger.isInsert || trigger.isUpdate ){

EventTriggerUtil.updateDescription(trigger.new);

}

class:

private static boolean Hassent = false;

public void updateDescription(List<Event> eventList){

List<Event> eventtoupdate = new List<Event>();

If(!HasSent){

for(event e:eventList){

Event eve =new Event(Id = e.Id);

eve.Description=eve.Notes_Preview__c;

eventtoupdate.add(eve);

HasSent=true;

}

if(eventtoupdate.size()>0){

update eventtoupdate;

}

since you are updating data on same object as trigger being fired , the trigger should be written on trigger.isBefore not trigger.isAfte.

so try as given below

trigger:

if(trigger.isBefore ){
