I've got a page that was originally designed for listing/selecting records from a datatable...

I'm using a custom controller to query the "Payment" object I want and then I stick those in a wrapper so I can select the ones I want to process.

Client came back and said they'd like inlineediting, so I stuck it in, but can't figure out how to update the data once it's been changed.

I think the problem is that when I edit a piece of data, it's never "set" back in the list, but I'm stumped on doing that...might just be a long day.  Anyone have a thought? 

I'm sure I just need to stick a {set;} somewhere, but I just don't know where...

Thanks.

here's the vf page code:

<apex:pageblocksection title="Request Refunds" 
	columns="1" 
	collapsible="FALSE"	
	>

<apex:dataTable value="{!payments}" var="p" width="100%">

    <apex:column >        
        <apex:inputCheckbox value="{!p.selected}" id="checkedone" disabled="{!p.pay.Refund_Requested__c}">
            <apex:actionSupport event="onclick" action="{!GetSelected}" rerender="totalsection"/>
        </apex:inputCheckbox>
    </apex:column>
    
    <apex:column headervalue="Reference Nbr" value="{!p.pay.Name}" />       
    <apex:column headervalue="Payment Date" value="{!p.pay.Payment_Date__c}" />
    <apex:column headervalue="Payment Type" value="{!p.pay.Payment_Type__c}" />
    <apex:column headervalue="Status" value="{!p.pay.Payment_Status__c}" />
    <apex:column headervalue="Amount" value="{!p.pay.Payment_Amount__c}" />
    <apex:column headervalue="Refund Requested" value="{!p.pay.Refund_Requested__c}" />
    <apex:column headervalue="Type" value="{!p.pay.RecordType.Name} - {!p.pay.Refund_for_Payment__r.Name}"/> 
<apex:inlineEditSupport event="ondblClick" 
                        showOnEdit="saveButton,cancelButton" hideOnEdit="editButton" />
</apex:dataTable>
        
</apex:pageblocksection>

 I tried to give the simplified version...okay, the controller:

public with sharing class ctrl_Refund {
List<paymentwrapper> PaymentList  = new List<paymentwrapper>();
List<CCPayment__c> SelectedPayments = new List<CCPayment__c>();

public ctrl_Refund() {
	             //get thelist of payments Payments
                list<CCPayment__c> plist = [select p.id,p.name,p.payment_status__c, p.payment_date__c, 
                                            p.payment_amount__c, p.payment_type__c, p.refund_requested__c, 
                                            p.opportunity__c,p.Refund_for_Payment__r.Name,
                                            p.RecordType.Name
                                            from CCPayment__c p 
                                            where 
											p.opportunity__c = :id];                                    
                for(CCPayment__c p : plist){
                        PaymentList.add(new paymentwrapper(p));
                }
                system.debug('### Out of for loop - PaymentList: ' + PaymentList);
                
if(PaymentList.size()>0){
		HasCollectedPayments = True;
	}
	else {HasCollectedPayments = False;}
}

public PageReference getSelected()
    {
                SelectedPayments.clear();
                for(paymentwrapper paywrapper : PaymentList){
                        if(paywrapper.selected == true && paywrapper.pay.Refund_Requested__c == false) {
                                selectedPayments.add(paywrapper.pay);
                        }
                }
                return null;
    }
	
public class paymentwrapper
            {
                public CCPayment__c pay {get; set;}
                public Boolean selected {get; set;}
                public paymentwrapper(CCPayment__c p)
                {
                    pay = p;
                    selected = false;
                }
            }	
}
