Does it work fine if you define AbstractBase as a MappedSuperclass ?

Maybe having inherited mapped properties coming from classes that are not mapped by Doctrine does not work well with entity inheritance.

the expected usage of Doctrine is that mapped properties should be declared in mapped classes (either entities or mapped super-classes)

@mpdude I've copied this code into Doctrine\ORM\Mapping\Driver\ReflectionBasedDriver again after v3.5.3 update, and all is working as usually

if ($this->isTransient($declaringClass)) {
    return isset($metadata->fieldMappings[$property->name]);
}

That does not make the code more correct 🫠

There must be a mapping misconfiguration somewhere in your code, where you have mapping attributes in a class that is neither an entity nor a mapped superclass.

@mpdude where is the right place to put the MappedSuperClass attribute? Into AbstractBase or AbstractAttachment? Keep in mind that both are abstract classes...

AbstractBase

I note all your classes come from different namespaces. Also that’s a pattern I’ve seen in other bug reports before.

Well, the main problem seems that #[ORM\MappedSuperclass] must be applied into an abstract class located under same namespace root.

We've solved just moving our AbstractBase from App\Shared\Domain\Model to App\Main\Domain\Model (where lives the class that implements ORM\InheritanceType)

Before v3.5.3 no error thrown, but I'm not 100% sure that was fully working too, because I've discovered that the discriminator column type was empty.

#[ORM\InheritanceType('SINGLE_TABLE')]
#[ORM\DiscriminatorColumn(name: 'type', type: 'string')]

Now we are updated to the latest version and the type column is filled according to the extended class.

this is not true. It must be applied in a class located in a namespace registered in the mapping configuration of the entity manager. But it can be a different namespace than the entity.

Ok, now I can see the real problem, thx @stof

The initial abstract class was located inside a namespace that was not registered.

😅 Good to hear that.

I was afraid that there might be in fact a bigger issue for a future me, given the other two similar-looking reports #11404 and #11488, plus I have an internal issue pending investigation where a co-worker made similar claims.
