Hi Rajesh

I am still unable to get this working, ive been on it for hours!

Would it be possible for you to post the test class, or PM me for consulting to do some work?

Here is what I have

public class PresentationWithTicketTypeController {
 
    //added an instance varaible for the standard controller
    private ApexPages.StandardController controller {get; set;}
     // add the instance for the variables being passed by id on the url
    private miiEventV1__Presentation__c pres {get;set;}
    // set the id of the record that is created -- ONLY USED BY THE TEST CLASS
    public ID newRecordId {get;set;}
 
    // initialize the controller
    public PresentationWithTicketTypeController(ApexPages.StandardController controller) {
 
        //initialize the stanrdard controller
        this.controller = controller;
        // load the current record
        pres = (miiEventV1__Presentation__c)controller.getRecord();
 
    }
 
    // method called from the VF's action attribute to clone the pres
    public PageReference cloneWithItems() {
 
         // setup the save point for rollback
         Savepoint sp = Database.setSavepoint();
         miiEventV1__Presentation__c newPRES;
 
         try {
 
              //copy the project plan - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
