Hello,

Looking for help solving a simple issue that will most likely be a quick fix but yet I've spent too much time trying to crack it. The issue is that I have a pageblocktable with OpportunityLineItems, these can have their fields updated such as Qty and Discount. on the Qty and Discount field's onblur event  I perform an upsert of the OppLine so that the server can calculate the TotalPrice and other relevant fields. Once the save is done, I requery for the record to show the latest updated values from the server, BUT even though in the debug log I see that the record got updated, when I rerender the field (even tried rerendering the entire table) the value simply disappears as if by "magic". 

How can I get the row rerendered with the new values in the record??? Please assist! Below is code for controller and VF page where the issue seems to be happening:

VF page table: (NOTE: some fields that are static and do not get updated have been removed to downsize post length)

 <apex:outputPanel id="tablePnl">  
        <apex:pageblockTable value="{!OLIs}" var="OLI" id="OLIList" >
            <apex:column id="DelCol"> 
                {!OLI.Id}  -- {!OLI.TotalPrice}                   
                <apex:commandButton value="Delete" action="{!del}" rerender="tablePnl,detailPanel">
                    <apex:param name="delname" value="{!OLI.id}" assignTo="{!currOLIid}"/> 
                </apex:commandButton>          
            </apex:column>                    
            <apex:column headerValue="Quantity"> 
                <apex:inputField value="{!OLI.Quantity}"  id="fQTY" required="{!OLI.PriceBookEntry.Product2.Name != null}"  >
                    <apex:actionSupport event="onblur" rerender="tablePnl,fUnitCost,fProfit,fTotalPrice,fDiscPct,fDiscAmt" action="{!saveOLI}" disabled="{!(OLI.Quantity == null || OLI.Quantity <= 0) || (OLI.UnitPrice == null || OLI.UnitPrice <= 0)}"  >
                        <apex:param name="currOLIQty" value="{!OLI.Id}" assignTo="{!currOLIid}"/>
                    </apex:actionSupport>
                </apex:inputField>
            </apex:column>             
            <apex:column headerValue="Unit Cost" >
                <apex:inputField value="{!OLI.Unit_Cost__c}" id="fUnitCost"/>       
            </apex:column>
            <apex:column headerValue="Sales Price ex VAT"">
                <apex:inputField value="{!OLI.UnitPrice}"/>
            </apex:column>
            <apex:column headerValue="Line Disc Pct.">
                <apex:inputField value="{!OLI.Discount}" id="fDiscPct">
                <apex:actionSupport event="onblur" rerender="fUnitCost,fProfit,fTotalPrice,fDiscPct,fDiscAmt" action="{!saveOLI}" disabled="{!(OLI.Quantity == null || OLI.Quantity <= 0) || (OLI.UnitPrice == null || OLI.UnitPrice <= 0)}"  >
                        <apex:param name="currOLIQty" value="{!OLI.Id}" assignTo="{!currOLIid}"/>
                    </apex:actionSupport>
                </apex:inputField>
            </apex:column>
            <apex:column headerValue="Total Price">
                    <apex:outputField value="{!OLI.TotalPrice}" id="fTotalPrice"  />
            </apex:column>         
        </apex:pageBlockTable>
    </apex:outputPanel>

 And this is the code in the controller that performs the saveOLI action (saving the record):

    public PageReference saveOLI() {
        system.debug('###currOLI: ' + currOLI);
        currOLI.TotalPrice = null;
        try{
        upsert currOLI;
        currOLI = loadOLI(currOLI);
        for(OpportunityLineItem o: OLIs) {
            if(o.id == currOLI.id) {
                o = currOLI;
                system.debug('###After saveOLI OLIs(o) from currOLI: ' + o);
            }
        }
        }catch(Exception e) {
            ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error saving Opportunity Product: ' + e.getMessage());
            ApexPages.addMessage(myMsg);
        }
        return null;
    }
