my vf code:

            <apex:inputfield value="{!Opportunity.StageName}" >
                <apex:actionSupport id="oprstage" event="onchange" action="{!setProbability}" rerender="productInfo" immediate="TRUE" />
            </apex:inputfield>
            <apex:inputfield value="{!Opportunity.Day_Rate__c}" id="oprrate"/>
            <apex:inputfield value="{!opr.Probability}" id="oprprob"/>

controller:

public with sharing class OpportunitySave {
    public string probability {get;set;}
    public Opportunity opr {get;set;}
    public OpportunitySave(ApexPages.StandardController controller) {

    }
    public PageReference setProbability(){
        opr.Probability = '30%';
        return null;
    }
}

used jquery to fix it...fpor reference:
  
function setProb(input){
     var stage =  input.value;
     if (stage == 'Suspect/Prospect') jQuery( '[id$=oprprob]' ).val(0);
     if (stage == 'Opportunity Identified') jQuery( '[id$=oprprob]' ).val(10);
     if (stage == 'Opportunity Qualified') jQuery( '[id$=oprprob]' ).val(20);
     if (stage == 'Proposal Submitted') jQuery( '[id$=oprprob]' ).val(30);
     if (stage == 'Shortlisted') jQuery( '[id$=oprprob]' ).val(40);
     if (stage == 'Preferred Bidder') jQuery( '[id$=oprprob]' ).val(60);
     if (stage == 'Indication to go ahead') jQuery( '[id$=oprprob]' ).val(80);
     if (stage == 'Closed Won') jQuery( '[id$=oprprob]' ).val(100);
     if (stage == 'Closed Lost') jQuery( '[id$=oprprob]' ).val(0);
     if (stage == 'Opportunity Identified (IC Only)') jQuery( '[id$=oprprob]' ).val(30);
     if (stage == 'Opportunity Qualified (IC Only)') jQuery( '[id$=oprprob]' ).val(40);
     if (stage == 'Proposal Submitted (IC Only)') jQuery( '[id$=oprprob]' ).val(70);
     if (stage == 'Won not signed (IC only)') jQuery( '[id$=oprprob]' ).val(95);   
     //oprstage();
    }

apex code:

<apex:inputfield value="{!Opportunity.StageName}" onChange="setProb(this)" required="true" >

Hi Prabhu,

Remove  immediate="TRUE" attribute in actionsupport and rerender the correct block id. If not this works, share your code.

thanks arun, what wud typically gointo the rerender ? i'm bit confused with that...any help on it please?
Arunkumar RArunkumar R
Rerender used to render a particular region instead of whole page refresh. 

You can have a below example, this will give you a clear thought.

tried it but getting an error in VF page:


System.NullPointerException: Attempt to de-reference a null object
Error is in expression '{!setProbability}' in page opportunitysave: Class.OpportunitySave.setProbability: line 8, column 1
Class.OpportunitySave.setProbability: line 8, column 1
Arunkumar RArunkumar R
could you share your code?

standard controller class is:

public with sharing class OpportunitySave {
    public string probability {get;set;}
    public Opportunity opr {get;set;}
    public OpportunitySave(ApexPages.StandardController controller) {

    }
    public PageReference setProbability(){
        Opportunity.Probability = 30;
        return null;
    }
}

    <apex:pageBlock title="Opportunity Edit" mode="edit"  >

used jquery to fix it...fpor reference:
