How to show fields from multiple objects in Visualforce Page string

Question

I have created a visualforce page to display as txt, so that when a button is clicked, a txt file is downloaded to the computer. I need this txt document to be a comma-separated collection of fields.

The main object is Loan, which can have multiple Legal_Entities and Loan_Collateral2 records. I started with using the standardController and then writing an extension to query and gather the child records.

Now I don't know how to get the fields from the query into the visualforce page.

And I've been staring at it for so long, it is making less and less sense.

The following code presents me with "Unknown property 'LLC_BI__Loan__cStandardController.borList'"

VFP

    <apex:page contentType="text/plain#{!LLC_BI__Loan__c.name}.txt" 
           standardController="LLC_BI__Loan__c" extensions="transportExtend">
    <apex:variable var="lo" value="{!LLC_BI__Loan__c}"/>
    <apex:variable var="b" value="{!borList}"/>
test fields: {!b.name},{!$User.Officer_Codes__c},
    <!--1ApplicationCode-->CCD,<!--2LoanNumber-->{!lo.LLC_BI__lookupkey__c},<!--3Mod-->90,<!--4IntType-->1,
    <!--5PmtType-->0,<!--6CallCode-->{!lo.Purpose_Code__c},<!--7BranchNo-->{!lo.LLC_BI__Branch__r.LLC_BI__Branch_Id__c},
    <!--8ProceedsAmtBLANK-->,
</apex:page>

APXC

public with sharing class transportExtend{

    public ApexPages.StandardController stdController {get;set;}
        
    public Id currentLoanId {get;set;}
    
    public transportExtend(ApexPages.StandardController ctrl){
        LLC_BI__Loan__c loanObject = (LLC_BI__Loan__c)ctrl.getRecord();
        currentLoanId = loanObject.Id;
        stdController=ctrl;
    }
    
    public List<LLC_BI__Legal_Entities__c> getBorrower(){

Answer 1

The error you are getting is telling you that {!borlist} is not a visible (public) property in your Apex controller

Change the VF page to reference the public method getBorrower as follows

<apex:variable var="b" value="{!borrower}"/>

VF compiler will prepend the {!borrower} to become getBorrower
