Hi All,

I am working on a module which requires me to send an attachment of the invoice as a pdf once i click a button and below is the code for your reference. The problem here is that the same code works flawlessly on the platform but it fails to work on communities with the following error "Error occurred while loading a Visualforce page" .Also, i am calling this method in another method that has void as its return type.
Would be glad if someone can help me on this.

public pagereference SendEmail(){
    // Define the email
    System.debug('inside SendEmail method:'+Inv.invoice_status__c);
    Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
    PageReference pdf = Page.InvoicePagePDF;
   
    pdf.setRedirect(true); 
      Invoice__c InvoicemailVar = [ Some Query ];
      String emal = InvoicemailVar.Email ;
      system.debug('mail id of contact ' +emal );
     /*START Bharath Kumar - March 28,2016 - Skip this section */
    if (!Test.isRunningTest()){
    Blob b = pdf.getContent();
// Create the email attachment
    Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();
    efa.setFileName('Invoice.pdf');
    efa.setBody(b);
    String addresses;
    email.setSubject( 'Invoice' );
    string[] test = new String[] {emal};
    email.setToAddresses( test  );
    email.setPlainTextBody(' Hi, your invoice has been generated' );
    email.setFileAttachments(new Messaging.EmailFileAttachment[] {efa});
// Send it
    Messaging.SendEmailResult [] r =
    Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});
    }
       
 
         ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.CONFIRM,'Invoice has been mailed.'));
            return null;
   }

 

I created a VF Page so the view for a custom object would show the related list as tabs. The page works great within the full app, but it gives the error "Error occurred while loading a Visualforce page" when any customer portal(coummunity) users tries to view a record in the object.  I turned on debug, but it does not give me any details on the error. 

 

The portal user profile does have the VF page assigned to it. 

 

Below is the code for the page and below that is the debug log. 

 

Any help would be much appreciated.
