standard controller and extension controller referencing issues

Hello,

I have a wrapper extension class that's intended to bring back grandchild records for a pageblock table within a Visualforce page. However, I keep getting errors when trying to save the Visualforce page referencing the extension controller. I'm not sure if there's a problem with the extension controller or the Visualforce page? Please see code below, any help is greatly appreciated!

VF Page:

<apex:page standardController="Consolidated_Invoicing__c" extensions="WrapperSarah"  renderas="pdf">

Extension Controller:

public class WrapperSarah{ 
private final Consolidated_Invoicing__c consinvs;
    public WrapperSarah(ApexPages.StandardController stdController) {
this.consinvs = (Consolidated_Invoicing__c)stdController.getRecord();
    }

Can provide the full code if needed but only getting errors after this has been added in following a salesforce guide.

Thanks!

Hi Sarah

Please use this class.

public class WrapperSarah{ 

private final Consolidated_Invoicing__c consinvs;
    public WrapperSarah(ApexPages.StandardController stdController) {
       this.consinvs = (Consolidated_Invoicing__c)stdController.getRecord();

Hi Sarah,

 

Please send full code and error message.

 

Thanks,
Raj VakatiRaj Vakati
what is the error message?

Change your code like below and try once

public class WrapperSarah{ 
public Consolidated_Invoicing__c consinvs;
    public WrapperSarah(ApexPages.StandardController stdController) {
this.consinvs = (Consolidated_Invoicing__c)stdController.getRecord();
    }

This should then produce a consolidated invoice pdf showing a table of related invoices (child) and treatments(grandchild) to the Consolidated Invoice (Parent) but this is all that i'm getting when previewing with a record id with no table data showing:

Thanks for the class, this appears to be working fine but the visualforce page only seems to be working with "WrapperSarah" as the Controller rather than as an extension Controller. 

As a controller, the table is successfully displayed with the required data using a VF page starting with:

<apex:page Controller="WrapperSarah" renderas="pdf">

But I need to use the wrapper as an extension as per my original visualforce page code in order to reference standard controller functionality too.

<apex:page standardController="Consolidated_Invoicing__c" extensions="WrapperSarah"  renderas="pdf">

This doesn't seem to be instantiating the extension class as no table is diplayed on the pdf. Is there anything obvious that I'm missing with referencing the extension?

Thanks so much for your help!

I'm not sure if it's possible to use a standard controller and an extention controller to reference fields on the grandparent object
