pvm's Issues

There seems to be a logic error here

$ormToken = $this->objectManager->getRepository($this->tokenClass)->findOneBy([
'id' => $id,
]);
if (false == $ormToken) {
throw new \LogicException(sprintf('The token with id "%s" could not be found', $id));
}
/** @var \Formapro\Pvm\Doctrine\Process $ormProcess */
$ormProcess = $this->objectManager->getRepository($this->processClass)->findOneBy([
'id' => $ormToken->getProcessId(),
]);
if (false == $ormToken) {
throw new \LogicException(sprintf('The process with id "%s" could not be found', $ormToken->getProcessId()));
}

It seems that both $ormToken is being verified on lines 132 and 141, but it seems that $ormProcess is more logical on line 141.

examples is doesn't work

i follow the docs to examples ,but is doesn't work ,the error strack :

Formapro\Pvm\Doctrine\DoctrineDAL::__construct() must be an instance of Doctrine\Common\Persistence\ObjectManager, instance of Doctrine\ORM\EntityManager given

"formapro/pvm": "^0.4.7"
"symfony/yaml": "3.*"
"doctrine/orm": "^2.6.2",

I am following your documentation example here:
https://pvm-demo.forma-pro.com/demo/store-to-mysql

I am however using more recent versions. I've had to update a few parts to make it work.

I'm now stuck on this line:
$doctrineDal = new DoctrineDAL($em, OrmProcess::class, OrmToken::class);

According to your example Argument 1 should be the EntityManager instance but for some reason it is expecting ObjectManager.

Everything seems to run fine up until this point...

$config = new Configuration();
$config->setAutoGenerateProxyClasses(true);
$config->setProxyDir(\sys_get_temp_dir());
$config->setProxyNamespace('Proxies');
$config->setQueryCacheImpl(new ArrayCache());
$config->setMetadataCacheImpl(new ArrayCache());

$driver = new MappingDriverChain();
$annotationDriver = $config->newDefaultAnnotationDriver([BASE_DIR . 'app/StoreToDoctrine'], false);
$driver->addDriver($annotationDriver, 'MYAPP\StoreToDoctrine');

$xmlDriver = new SimplifiedXmlDriver([
    realpath(BASE_DIR.'vendor/formapro/pvm/src/Doctrine/mapping') => 'Formapro\Pvm\Doctrine',
]);
$driver->addDriver($xmlDriver, 'Formapro\Pvm\Doctrine');

$config->setMetadataDriverImpl($driver);

$encryption = new Encryption();
$dbName = 'test';
$credentials = array (
    'test' => array (
        'username' => <removed>,
        'pw' => <removed>,
        'connstr' => <removed>,
        'host'  => <removed>
    )
);

$conn = [
    'url' => 'oci8:' . $credentials[$dbName]['username'] .':'. $credentials[$dbName]['pw'] . '@' . $credentials[$dbName]['host'] ."/" . $credentials[$dbName]['connstr'],
    'user' => $credentials[$dbName]['username'],
    'password' => <removed>,
    "connectstring" => $credentials[$dbName]['host'] ."/" . $credentials[$dbName]['connstr']
];

$entityManager = EntityManager::create($conn, $config);

/* Formapro PVM */

use Formapro\Pvm\DefaultBehaviorRegistry;
use Formapro\Pvm\Doctrine\DoctrineDAL;
use Formapro\Pvm\ProcessEngine;
use Formapro\Pvm\Token;
use Formapro\Pvm\ProcessBuilder;

use MYAPP\Doctrine\OrmProcess;
use MYAPP\Doctrine\OrmToken;

$schemaTool = new SchemaTool($entityManager);
$schemaTool->updateSchema($entityManager->getMetadataFactory()->getAllMetadata());

Then I add this:

$doctrineDal = new DoctrineDAL($entityManager, OrmProcess::class, OrmToken::class);

And get the following error:

Fatal error: Uncaught TypeError: Argument 1 passed to Formapro\Pvm\Doctrine\DoctrineDAL::__construct() must be an instance of Doctrine\Common\Persistence\ObjectManager, instance of Doctrine\ORM\EntityManager given, called in <removed>/scripts/myapp.php on line 77 and defined in <removed>/vendor/formapro/pvm/src/Doctrine/DoctrineDAL.php:28

#1 {main}
  thrown in <removed>/vendor/formapro/pvm/src/Doctrine/DoctrineDAL.php on line 28

I've only been able to find this possible solution online...

https://stackoverflow.com/questions/45678333/construct-must-be-an-instance-of-doctrine-common-persistance-objectmanager

But I'm not sure what they mean or how to resolve this.

Roadmap request

I am interested in using this library, i noticed there are some breaking changes in master (between v0.2.4 and master) are there many more breaking changes planned for the next release? or have you thought about what might be left before you get to version 1 of this library?

examples are not working anymore with version > 0.2.0

Version: 0.2.3

example: https://github.com/formapro/pvm/blob/master/docs/sequence-example.md

missing trait

trait CreateTrait must be placed in Yadm directory. But now it just in src/ directory
