Hi There,

I have a controller which is for an object, that has many children objects looking it up. The controller wraps the two children into a datatble. So far, everything on the page works, if I am inserting these records. I was wondering, what I would have to change within the controller, so that it can be used for editing records as well.

By editing, I essentially mean displaying the page, with all the inpput fields filled and the datatable full of child objects, how it looked just before save. I think i need to access the Fin record and all loan split and loan security records that look the Fin record up.

I am not sure how to phrase this, a point in the right direction would be much appreciated.

this is my controller:
 

public class FinanceNew{
    
    public Finance__c Fin { get; set; }
    public Finance_Loan_Security__c LoanSecurity { get; set; }
    public Finance_Loan_Split__c LoanSplit { get; set; }
    
    
    //Wrapper multi add try to implement
     public List<FinLoanSplitWrapper> wrappers {get; set;}
 public static Integer toDelIdent {get; set;}
 public static Integer addCount {get; set;}
 private Integer nextIdent=0;
 
 //\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Wrapper 2 identical - 1
       public List<FinLoanSecurityWrapper> wrappers2 {get; set;}
 public static Integer toDelIdent2 {get; set;}
 public static Integer addCount2 {get; set;}
 private Integer nextIdent2=0;
 //\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Wrapper 2 identical - 1
 
 ////////////////test
 
 public decimal AggregateLoanAmount{get;set;}
 public integer LoanSplitSize{get;set;}
 
 public void calculation()
{
AggregateLoanAmount = 0.00;
LoanSplitSize = 0;
  for (FinLoanSplitWrapper wrap : wrappers)
  {
  if(wrap.FinLoanS.Loan_Amount__c == null){
  wrap.FinLoanS.Loan_Amount__c = 0.00;
  }
   LoanSplitSize = LoanSplitSize + 1;
   AggregateLoanAmount = AggregateLoanAmount + wrap.FinLoanS.Loan_Amount__c;
  }
  

}
