Does someone (@sonata-project/contributors ) is familiar with
https://github.com/sonata-project/sonata-doctrine-extensions/blob/1.x/src/Mapper/DoctrineCollector.php#L119-L130
and
https://github.com/sonata-project/sonata-doctrine-extensions/blob/1.x/src/Mapper/ORM/DoctrineORMMapper.php#L68-L83

One method is doing

$this->associations[$class][$type][] =

the other is doing

$this->associations[$class][$type] =

Is there a bug or does it means that DoctrineORMMapper::addAssociation can only be called once and should pass array<array<string, mixed>> maybe ?

[VincentLanglet]

Looking at the usage, the DoctrineCollector seems right
https://github.com/sonata-project/SonataPageBundle/blob/5bd4b5cde9833b25ce15e323a9fc5a7b69d18d3d/src/DependencyInjection/SonataPageExtension.php#L543-L561

So I updated the phpdoc of the DoctrineORMMapper to follow the same strategy.

But I found no usage of DoctrineORMMapper, should we deprecate this class ?

Please review @sonata-project/contributors

Could you please rebase your PR and fix merge conflicts?

This should be adapted

[jordisala1991]

we should stop using max, on phpstan 1.0 max is level 9, currently is level 8

[VincentLanglet]

Not a big deal since it require the bump from ^0.12 to ^1.0

[jordisala1991]

Fine, it is either changing it now or later, most likely we are not going to pass level 9 that easy
