Hi ,
I have a Visual force page and Need a Custom Save and New Functionality,

Opportunity (Parent Object)        -------      Client_Discovery__C (Child Object)   , 
Client_Discovery__C (Parent Object) ----- Client_Site__C (Child Object)
Client_Site__C (Parent Object) ------ Client Supplier (Child Object)

What i am trying to achive with my visual force page is , On Opportunity related list i have New Client Disovery Button withich is Standard  Visual Page.

When user Clicks New Client Disocvery and enters data

and hits save page is Redirected to new Visual Force page where users can create Client Site and Multipole Supplier at the Same time .



Here when user finishes enetring data He needs to hit Save & New and again go to the same VF page where he just hit save & new . I am able to redirect to that page but missing the Parent ID.

First Vf Page Standard page ClientQuestionarrie with Custom Save method in Client Questionarrie Controller.

public with sharing class ClientQuestionarrie {

    Apexpages.StandardController controller;
    public Client_Discovery__c myCustomObject;
    public ClientQuestionarrie(ApexPages.StandardController sc)
    { 
    this.controller = sc;
    myCustomObject = (Client_Discovery__c) sc.getRecord();  
    }

    public PageReference SaveQuestionarrie()
    {
          upsert myCustomObject;
          Pagereference ref = new Pagereference('/Apex/ClientSite');
          ref.getParameters().put('Client_Discovery__c', myCustomObject.Id);
          ref.setRedirect(true);
          return ref;
    }
  
  
}

public with sharing class ClientSiteExt {

    public ClientSiteExt(ApexPages.StandardController controller) {
        Client_Site__c c = (Client_Site__c) controller.getRecord();
        c.Client_Discovery__c  = ApexPages.currentPage().getParameters().get('Client_Discovery__c');
    }

}
