I'm working on a custom payment method on X-cart 5, when placing order I got this exception in log file:

This exception happens when transaction is sucess.



Here is the simplified version of the processor:

<?php

class NabXML extends \XLite\Model\Payment\Base\CreditCard
{
    protected function doInitialPayment()
    {        
        $txnID = time();
        $this->transaction->setStatus($this->transaction::STATUS_SUCCESS);
        $this->setDetail('transId', $txnID, 'Transaction ID');

        return static::COMPLETED;
    }
}

install.yaml file:

XLite\Model\Payment\Method:
  - service_name: Nab XML
    class: Module\SydneyEcommerce\NabXML\Model\Payment\Processor\NabXML
    type: C
...

I have multiple questions:
- Where can I find a document about developing a custom payment method?
- How can I debug and fix above exception?
- Is there a way for dev like me get full X-Cart code for self-hosting and developing stuffs?

First point: links like https://devs.x-cart.com/webinars_and_video_tutorials/webinar_3_-_21_aug_2014_-_payment_gateway_creation.html and https://devs.x-cart.com/changing_store_logic/creating_a_settings_page_for_a_payment_method.html can help, maybe?


Second: try to dump any relevant variables.




Third: x-cart's source code used to be downloadable...
