enter image description hereI want to prepoulate Name field on opportunity with text as "System Generated".

I have written created a VF page

<apex:page standardController="Opportunity" extensions="DefaultOpprtunityNameController" action="{!redirect}"/>

and its controller as

public with sharing class DefaultOpprtunityNameController {

public DefaultOpprtunityNameController(ApexPages.StandardController controller) {


public PageReference redirect() {
    PageReference pr = new PageReference('/006/e');
    Map<String, String> m = pr.getParameters();
    // Keep existing parameters
    // Add Opportunity name parameter
    m.put('opp3', '<System Generated>');
    m.put('opp11', 'Requested Info');
    m.put('opp12', '25');
    // Turn off the override so you go to the default UI page (and not an infinite loop)
    m.put('nooverride', '1');
    return pr;


And overrided standerd Opportunity "New" button with the above VF page

But I am getting an error

Error: Invalid Data.
Review all error messages below to correct your data. The page you submitted was invalid for your session. Please click Save again to confirm your change.

  • Are you getting the error when you click the "New" button or when you click the "Save" button after clicking "New"? – BarCotter Sep 11 '15 at 10:25
  • I am getting error on click of new button on opportunity tab landing page. – Swapnil Kale Sep 11 '15 at 10:33
  • Wondering if it has to do with setting the probability to a string value. – Jenny B Sep 11 '15 at 11:30

The problem appears to be with grabbing the parameters from the page where the "New" button is clicked. Try eliminating this line and that should eliminate the error.

    That what I was seeing as well. I got the error to go away by removing the save_new parameter. – martin Sep 11 '15 at 15:30
