Pop Field Case to Field Case
Hi
I have a problem poppulate Field.
Email_Subject__c = Subject At before insert and subject = null
Error: Invalid Data.
Review all error messages below to correct your data.
Apex trigger ChangeEmail caused an unexpected exception, contact your administrator: ChangeEmail: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object: Trigger.ChangeEmail: line 13, column 52
trigger ChangeEmail on Case(before insert) { Set<Id> CaseIDs = new Set<Id>(); for (Case COT: trigger.new) { CaseIDs.add(COT.id); } Map<Id, Case> pSale = new Map<Id, Case>([SELECT a.id, a.Email_Subject__c,a.Subject FROM Case a WHERE a.id IN :CaseIDs]); for(Case fcon : Trigger.New){ if(fcon.Origin == 'Email'){ fcon.Email_Subject__c = pSale.get(fcon.id).Subject; } } }
Thank you
