Using simple Doctrine queries results in an paginator exception

[Kreyu]

Passing a QueryBuilder that returns simple results, such as:

$query = $repository->createQueryBuilder('product')
    ->select('product.name');

results in an exception:

RuntimeException: The Paginator does not support Queries which only yield ScalarResults.

this can be fixed by applying a hint with custom output walker to the query in the data table type builder:

class ProductDataTableType extends AbstractDataTableType
{
    public function buildDataTable(DataTableBuilderInterface $builder, array $options): void
    {
        $builder->getQuery()->setHint(
            \Doctrine\ORM\Query::HINT_CUSTOM_OUTPUT_WALKER, 
            \Doctrine\ORM\Query\SqlWalker::class,
        );
    }
}

This, however, can be handled automatically, see implementation in Sonata Admin:
