Unable to de-reference a null object
How can I write my class that if my destination lookup has the word “overseas” in it, it will set my orders received field to be true?
how to reference lookup name field in apex class?
public static void checkDestination(Map<Id, order__c> newOrders, Map<Id, order__c> oldOrders){ for(Id id : newOrders.keyset()){ if(newOrders.get(id).Destination__c != oldOrders.get(id).Destination__c && newOrders.get(id).Destination__r.Name.contains(‘OverSeas’)){ newOrders.get(id).Received__c =True; } } }Simple class but when I use contains() in my lookup reference: destination__r.Name, it throws an error:

Could you please try this -
You need to re-query in order to obtain fields on the parent record. Feel free to add the other fields to the SOQL too. Glyn Anderson (Slalom)
I like to use a "relatedData" map so that I don't lose the records in the trigger:
