How to add the Doctrine mapping of the Payum Core models?

[pdrosos]

Hello,

I am using Zend Framework with Doctrine and I would like to use the Payum Doctrine storage.
But I can't load the Payum's Core models mappings properly.
My Doctrine configuration inside the module where my entities are is:

'doctrine' => array (
    'driver' => array (
        'Payum_models' => array (
            'class' => 'Doctrine\ORM\Mapping\Driver\SimplifiedXmlDriver',
            'cache' => 'array',
            'paths' => array(
                __DIR__ . '/../../../vendor/payum/payum/src/Payum/Core/Bridge/Doctrine/Resources/mapping',
            )
        ),
        __NAMESPACE__ . '_entities' => array (
            'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
            'cache' => 'array',
            'paths' => array(
                __DIR__ . '/../src/' . __NAMESPACE__ . '/Entity',
            )
        ),
        'orm_default' => array(
            'drivers' => array(
                'Payum\Core\Model' => 'Payum_models',
                __NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_entities',
            )
        )
    )
),

And I receive the following error:

[Doctrine\Common\Persistence\Mapping\MappingException]
File mapping drivers must have a valid directory path, however the given path 0 seems to be incorrect!

Could you please help me how to configure the Payum Core Doctrine mappings correctly?
Thank you in advance!

Do you use payum/payum or payum/core only? The path to mapping files will be different in both cases.
