verifyPayment Failure

[endlichstudios]

When the verifyPayment function runs, it successfully ends with:
$this->onPaymentSuccess($row, $transactionId);

In the prcoessPayment function, I can grab the $Itemid by using:
$Itemid = JFactory::getApplication()->input->getInt('Itemid', 0);
Example: $Itemid = 1673

1. Is this correct?

I'm able to pass this ID back to the verifyPayment by using the url:
option=com_eventbooking&task=payment_confirm&payment_method=gwname&TransactionId=ZTACHCG0&Itemid=(ItemID From processPayment)
Example:
option=com_eventbooking&task=payment_confirm&payment_method=gwname&TransactionId=ZTACHCG0&Itemid=1673

When I load the ItemID loaded from the processPayment in the verifyPayment, $row is returned blank. I'm using this code and it will not load the data:
$id = $this->notificationData['Itemid'];
$row = JTable::getInstance('EventBooking', 'Registrant');
$row->load($id);

2. How should $row loaded if this is incorrect? Am I loading the Itemid incorrectly from the processPayment?

$Itemid is id of the active menu item, it is not id of the registration record, so if you want to have id properly passed:

1. Pass it in the URL:

option=com_eventbooking&task=payment_confirm&payment_method=gwname&id=ID_OF_RECORD&Itemid=1673

ID_OR_RECORD can be accessed via $row->id

2. In the code of verifyPayment method, you can get id by calling

$id = JFactory::getApplication()->input->getInt('id', 0);
$row->load($id);

That should work well

That works perfectly. After the verifyPayment function returns true, I'm left at a blank screen. Is there a confirmation page? I also noticed that if I go back to the even booking list, I still have the item in my cart. Is that supposed to be cleared out after the Payment was verified? How is that done?
