Help on Apex code that copy parent address to chlild adddress


Iam writing Apex code to create new contact record,when i select the parent account the address of selected account should copy to contact address fields  in edit page itself.


I wrote some code :



<apex:page sidebar="false" Controller="cont">
    <apex:form >  
    <apex:inputfield value="{!con.accountid}">
    <apex:actionSupport event="onchange" action="{!getrec}"/>



public class cont {
  public contact con {get; set; }
     public PageReference getrec() {
    contact cc=[select id,name from contact where id=:con.accountid ];
        return null;


Getting following Error:

Visualforce Error

System.NullPointerException: Attempt to de-reference a null object

Error is in expression '{!getrec}' in component <apex:page> in page parentaddr

This should solve your issue. You are not initializing the contact record. Please use Constructor to initialize the records.
