I'm working on the Event object in salesforce once the event get's inserted into salesforce it should create a record for me. It is working fine when the user create an events without attendee but once the user create an event with Attendee list it is not creating an record for the attendee. Below is the code for the creation of record. Please assist me with this.

Trigger eventUpdate on Event(Before Insert) { List < Time_Off__c > TimeOffs2Upsert = new List < Time_Off__c > (); for (Event evt: Trigger.new) { Time_Off__c TO = TimeOffMAP.containsKey(evt.WhatId) ? TimeOffMAP.get(evt.WhatId) : new Time_Off__c(); String STime = String.valueOf(evt.StartDateTime).split(' ')[1]; String ETime = String.valueOf(evt.EndDateTime).split(' ')[1]; Date StartDate = Date.newInstance(evt.StartDateTime.Year(), evt.StartDateTime.Month(), evt.StartDateTime.Day()); Date EndDate = Date.newInstance(evt.EndDateTime.Year(), evt.EndDateTime.Month(), evt.EndDateTime.Day()); Time StartTime = Time.newInstance(Integer.valueOf(STime.split(':')[0]), Integer.valueOf(STime.split(':')[1]), 0, 0); Time EndTime = Time.newInstance(Integer.valueOf(ETime.split(':')[0]), Integer.valueOf(ETime.split(':')[1]), 0, 0); TO.Start_Date__c = StartDate; TO.End_Date__c = EndDate; TO.Start_Time__c = StartTime; TO.End_Time__c = EndTime; TO.Type__c = 'Other'; TO.Reason__c = evt.Subject; TO.User__c = evt.OwnerId; TimeOffs2Upsert.add(TO); } if(TimeOffs2Upsert.size()>0) upsert TimeOffs2Upsert; }

Thanks
