tantonio BeforeDelete caused by: System.ListException: List index out of bounds: 0
Hi All,
I am having trouble figuring out why this is method id failing.
The row that is failing is when I try to add the values back into my list.
Line: deletedChangeRecords.add(deletedChangeRecords[0]);
Error: There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "Apex trigger scv_tfs_marquee caused an unexpected exception, contact your administrator: scv_tfs_marquee: execution of BeforeDelete caused by: System.ListException: List index out of bounds: 0: Class.svc_tfs.MarqueeDelete: line 105, column 1".
I think this has something to do with the fact that this method is called by a before delete trigger. Functionally, this method is supposed to update a record on a different object (ChangeRecord__c) before the delete occurs.
Thanks for any help on with this!

public static void MarqueeDelete(List<NI_MarqueeFeature__c> marqueeDelete){
List <ChangeRecord__c> deletedChangeRecords = new List <ChangeRecord__c>();
for (NI_MarqueeFeature__c md : marqueeDelete){//deletedChangeRecords contains trigger.new
List <ChangeRecord__c> deletedChangeRecord = [SELECT ID, LastMod__c FROM ChangeRecord__c WHERE ChangeRecord__c.ID__c = :md.Id LIMIT 1];
//If now matching change record is found, create one
//else update the existing one
if (deletedChangeRecord.size()<1){
ChangeRecord__c dm = new ChangeRecord__c ();
dm.ID__c = md.id;
dm.ObjectType__c = 0; //0 for Marquee Feature, 1 for CR, 2 for Product Release
dm.type__c = 2;
deletedChangeRecord.add(dm);
try {
insert dm;
} catch (system.DmlException e) {
system.debug (e);}
} else {
//Setting the value of LastModd__c to the last mod of trigger.new
deletedChangeRecord[0].LastMod__c = md.LastModifiedDate;
deletedChangeRecord[0].type__c = 2;
try {
deletedChangeRecords.add(deletedChangeRecords[0]);
} catch (system.DmlException e) {
system.debug (e);}
}
}
Changed
deletedChangeRecords.add(deletedChangeRecords[0]);
to
deletedChangeRecords.add(deletedChangeRecord[0]);
Problem solved. Thanks!
