Contract Object
Fulfillment Object (custom object)

When an opportunity gets closed won, a contract gets created via a button.
What i want is the a fulfillment record to also create automatically when the contract gets created
i also what the end screen to be the edit screen of the contract that was created

What i have so far: In my FinalConfg sandbox i have the following:
Custom Button on the opportunity: Create Contract
Visual Workflow:Called: "Auto Create Fulfillment"
Visualforce Page called: "CreateContract"
Visualforce Class called: "OpportunityFlowControl"

Everything seems to work fine except for the end screen, it does not return me to the edit screen of the Contract

Here is the code to my class:
public class OpportunityFlowControl {


    private final opportunity oppty;
    private final contract contract;
    public OpportunityFlowControl(ApexPages.StandardController stdController) {
      this.oppty = (Opportunity)stdController.getRecord();
    }
   
    Boolean testmode = Test.isRunningTest();


  //Calls referenced Flow below
  public Flow.Interview.Auto_Create_Fulfillment flAutoCreate { get; set; }

  //Gets Id of variables below from flow
  public String getopptyID() {
    if (flAutoCreate==null || ( testmode == true )){
     return '';
    }else{
      System.Debug('OpptyID:' + flAutoCreate.OpptyID);
      return flAutoCreate.OpptyID; //need test
    }
   
  }
 

  public String getcontractID() {
    if (flAutoCreate==null || ( testmode == true )) {
      return '';
      } else {
        System.Debug('ContractId:' + flAutoCreate.ContractCreate);
        return flAutoCreate.ContractCreate; //need test
    }
  }
 
  //Used for Flow finish location
  public PageReference getFinishPage(){
    if (flAutoCreate==null || ( testmode == true )) { return new PageReference('');}
   
    // need test case
    if(flAutoCreate.ContractCreate == null || ( testmode == true )){ 
    Contract cont;
    cont = [Select ID,Name,ContractNumber, createdDate from Contract where Opportunity__c =: this.oppty.Id Order by createdDate desc Limit 1];
      PageReference p = new PageReference('/' + cont + '/e');
      p.setRedirect(true);
      system.debug('Page Contract: ' + p);
      return p;
   
     
     
    }else {
   /* PageReference p = new PageReference('/' + getopptyID());
      p.setRedirect(true);
      system.debug('Page Opportunity: ' + p);
      return p; */
     
      Contract cont;
    cont = [Select ID,Name,ContractNumber, createdDate from Contract where Opportunity__c =: this.oppty.Id Order by createdDate desc Limit 1];
      PageReference p = new PageReference('/' + cont + '/e');
      p.setRedirect(true);
      system.debug('Page Contract: ' + p);
      return p;
    }
  }

 
}
