System.NullPointerException

The below code runs fine in testing environment, it's actually generating a PDF document.

 

 

public with sharing class PDFTransactionSlip {
public PDFTransactionSlip() {
}

public PDFTransactionSlip(ApexPages.StandardController controller) {
}

private String getXmlString(pb__Agreement__c c)
{
//datetime todayis = system.now();

double skcomdue = c.Buyer_Agency_Fee__c + c.Seller_Agency_Fee__c;
double premiumseller = c.pb__PurchaseListPrice__c - c.Inventory_Original_Price__c;

if(c.size() > 0){
pb__Agreement__c nc = c[0];
String xmlContent = getXmlString(nc);
Attachment attachment = new Attachment();
attachment.Body = Blob.valueOf(xmlContent);
attachment.Name = 'Transaction_Slip_' + c[0].Name + '_' + System.now() + '.XFDF';
attachment.ParentId = c[0].Id;
insert attachment;
PageReference contactPage = new PageReference('/' + c[0].id);
contactPage.setRedirect(true);
return contactPage;
}
PageReference contactPage = new PageReference('/' + ApexPages.currentPage().getParameters().get('id'));
contactPage.setRedirect(true);
return contactPage;
}
}

 

Problem is when try to execute it in production, it gives the following exception:

 


System.NullPointerException: Attempt to de-reference a null object

Class.PDFTransactionSlip.getXmlString: line 12, column 26 Class.PDFTransactionSlip.XFDFInit: line 85, column 29 External entry point
