 Description   

Steps to reproduce the problem?

  • A custom DBAL type, that extends a scalar build-in type e.g. DBAL\Types\StringType
  • convertToPHPValue of custom DBAL type returns an instance of a class (implements __toString method)
  • Custom DBAL type is used as primary key in an entity
  • initially persist entity and flush entity manager
  • modify entity (keep same primary key) and persist entity again causes:

    Warning: Illegal offset type in isset or empty in vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 2407

I guess the solution in Doctrine\ORM\Internal\Hydration namespace by explicit converting result of convertToPHPValue if result is not a scalar value.

This one will introduce way too much overhead. We don't really support identifiers that are custom object types.

What is the exact version of the ORM? I couldn't spot anything at line 2407.

Comment by Yves Berkholz [ 24/Jan/13 ]

I use a dev branch and updated the version since creation of the report, hence the line number changed to 2466.

UnitOfWork.php
} else {
	$entity = $this->newInstance($class);
	$oid    = spl_object_hash($entity);

	$this->entityIdentifiers[$oid]  = $id;
	$this->entityStates[$oid]       = self::STATE_MANAGED;
	$this->originalEntityData[$oid] = $data;

	$this->identityMap[$class->rootEntityName][$idHash] = $entity; // <- 2466

	if ($entity instanceof NotifyPropertyChanged) {
		$entity->addPropertyChangedListener($this);
	}

	$overrideLocalValues = true;
}

Ok, I understand the overhead problem. I only tried to create a custom enum type that is represented by a class.
But i solved this by converting the value within the getter/setter of entity class.
It would have been nice to do this in the DBAL type, but it works that way.
Therefore, you might close the report or move it on a far future version "wishlist".
Anyway, thank for your time.

Nevertheless the information you requested:
Composer: doctrine/orm [2.3.x-dev fdd0af3]
git reference: fdd0af34e6fced967b8751bc3e4792c11ef86d57

Additionally, exception trace might help

This works in this recent commit here, 0864ab8adac5c31d5ba97f0eb6792e5431a75b70. Should have worked before as well. Can you verify?

Comment by Benjamin Eberlei [ 01/May/13 ]

Related to DDC-1998, tests this behavior

Comment by Boy Baukema [ 28/Aug/13 ]

I'm still getting this issue, even after upgrading to 2.4.0-RC2.

Comment by Marco Pivetta [ 28/Aug/13 ]

Just a note: this is broken since 2.4 because before 2.4 we didn't convert meta fields via DBAL types. If your identifier is an object this will probably be the problem. We could cast it to string though.
