I am checking in the Cases list in my trigger, for record type Id and only if case is of that particular Record Type do I want a SOQL query to run.

But since a list is empty it throws a Null Pointer error. How can I prevent this?

if(cases[0].RecordTypeId == 'RecordTypeId') {

    cases_Creative = [SELECT Id, CaseNumber,Counter_Survey__c FROM Case Where RecordTypeId ='RecordTypeId' and Counter_Survey__c != null and createdDate = Last_N_Days:10 order by Counter_Survey__c desc limit 1];
  }

It sounds like you may need to bulkify your code, because multiple records could occur in a trigger. That said, to solve your immediate problem, you just need to use the && shortcircuit operator:

if(!cases.isEmpty() && cases[0].RecordTypeId == 'RecordTypeId') {

  • Thanks for the reply SFDCFOX. But getting the same null Pointer error. – Abhishek Apr 12 '17 at 13:48
  • Did you define cases? Try adding System.debug(cases == null); before the if statement and see if it ends up being null in the debug logs. – battery.cord Apr 12 '17 at 14:14
  • @battery.cord: Debug says 'false' when I put system.debug before if statement with cases == null. thanks! – Abhishek Apr 12 '17 at 14:31
  • Hey @battery.cord any pointers here please. – Abhishek Apr 13 '17 at 8:44

    @Abhishek Are you sure you're on the right line number, then? Maybe it's actually a completely different line? Assuming cases == null was false, then neither line is the problem. – sfdcfox Apr 13 '17 at 12:36
