Apex Trigger

I am missing a processing step regarding Apex Triggers.  I am attempting to create a trigger for the Account object. The logic is validating that the text field TrackerOrgType__c is not null then append the string to the multi select field Organization_Type__c field. Currently the error ,"Apex trigger AccountOrgUpdate caused an unexpected exception, contact your administrator: AccountOrgUpdate: execution of AfterUpdate caused by: System.ListException: List index out of bounds: 1: Trigger.AccountOrgUpdate: line 4, column 28".  I am not sure why the list is out of bounds when I am only working with 1 record. Would anyone like to shed some light on this?

 

trigger AccountOrgUpdate on Account (after insert, after update) {
		//Organization Type
		//TrackerOrgType
		Account ac = trigger.new[1];
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
			
		}
}

Use before instead of after in trigger like this (before insert, before update)

 

try this 

 

trigger AccountOrgUpdate on Account (before insert, before update) {
		//Organization Type
		//TrackerOrgType
		Account ac = trigger.new[0];
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
			
		}
}

Try this,

 

 

trigger AccountOrgUpdate on Account (after insert, after update) {
		//Organization Type
		//TrackerOrgType
		for(Account ac: trigger.new){
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
			
		}}
}

Use this instead

 

 

trigger AccountOrgUpdate on Account (after insert, after update) {
		//Organization Type
		//TrackerOrgType
		Account ac = trigger.new[0];
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
			
		}
}

  Butthis trigger of your will work only for single record, if you want to write it for bulk use this

 

 

trigger AccountOrgUpdate on Account (after insert, after update) {
		//Organization Type
		//TrackerOrgType
		for(Account ac : trigger.new) {
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
                } 
			
		}
}

Now I am getting the error, "Review all error messages below to correct your data.
Apex trigger AccountOrgUpdate caused an unexpected exception, contact your administrator: AccountOrgUpdate: execution of AfterUpdate caused by: System.FinalException: Record is read-only: Trigger.AccountOrgUpdate: line 15, column 4" when I attempt to use 

trigger AccountOrgUpdate on Account (after insert, after update) {
		//Organization Type
		//TrackerOrgType
		Account ac = trigger.new[0];
		if (ac.TrackerOrgType__c != null){
			ac.Organization_Type__c = ';'+ac.TrackerOrgType__c;
			
		}
}

The reason for this is in after trigger trigger.new is not updatable.

That makes perfect since, but now I discovered it is overwriting the Organization_Type__c field where as I was attempting to append. Is there a way to accomplish this?

I found that I can read in the Organization_Type__c into a Stirng variable and then reassign the Organization_Type__c field the variable plus the Tracker_Org_type__c. 

trigger AccountOrgUpdate on Account (before insert, before update) {
		//Organization Type
		//TrackerOrgType
		Account ac = trigger.new[0];
		if (ac.TrackerOrgType__c != null){
			String acc = ac.Organization_Type__c;
			ac.Organization_Type__c = acc+';'+ac.TrackerOrgType__c;
			
		}
}
