Help Needed with Apex Class: Multi-Select field not populating
I could use some help with correcting an apex class I have. The apex class copies values of fields from one object to another. I have a field called Request_Type2__c that was a picklist field. I had to convert this over to a multi-select picklist and now the apex class is not working. The values don't copy over. How can I rewrite this so that the values copy over? There are only 3 possibles values for the field: Media Plan; Art; Digital
Here is my class (the part in red is the part not working, both fields are Multi-Select with the same possible values):
public class OppSaveAttach{ ApexPages.StandardController controller; public OppSaveAttach(ApexPages.StandardController con){ controller = con; } public PageReference save() { Opportunity opp = (Opportunity)controller.getRecord();
