DevSF list error in visualforce page
Hi friends,
Hello everyone,
I am creating an invoice PDF.
I have two custom objects
1) Invoice__c
2) Invoice_Product__c
These 2 objects have master detail relationship between them (Invoice_Product__c is child object)
Here, i am writing a visualforce page on parent object (Invoice__c) where i need to get the values of my child object (Invoice_Product__c).
I was unable to retrieve child(Invoice_product__c) fields on invoice__c.
Error : Error: Unknown property 'VisualforceArrayList.Quantity__c'
My CODE :
<apex:repeat value="{!Invoice__c}" var="inv" id="theRepeat">
<tr style="font-size:16px;height:300px;vertical-align:text-top;Font-family:Verdana,Arial;">
<td style="border-left:1px solid;border-top:none;border-right:none;border-bottom:none;text-align:center;"><apex:outputText value="{!inv.Invoice_Products_r.Quantity__c}"/></td>
I could not take repeat value as {!Invoice.Invoice_Product__c} because evenly i am using invoice fields also.
I have checked with all these things but its not working.
1) invoice__c.Invoice_product__r. ===========> error : Unknown property 'VisualforceArrayList.Quantity__c'
2) Inv.Invoice_products__r ===================> Error : Unknown property 'Integer.Invoice_Products__r'
3) created a list in my controller and used its instance (i.Quantity__c) =======> Unknown property 'Invoice__cStandardController.i
How do i resolve this.
How can we use invoice_product fields on Invoice.
Please can anyone help me out of this...!

public class myController{
public List<Invoice_Products__c> invoicesProList {get;set;}
public String invoiceId;
public class myController(){
invoicesProList = new List<Invoice__c>();
invoicesProList = [select id, Quantity__c from Invoice_Products__c Where Invoice__c = :invoiceId];
}
}
where variable invoiceId stores the actual Id of the invoice for which you want the invoice product. You have replace that with actual id.
Let me know if this helps.
