symfony - 特定のノード内のドキュメントを選択する Doctrine PHPCR-ODM Query Builder

Question

次のノードがあります。

/
/applications
/applications/1
/applications/1/pages [contains Page documents]

Pagenode 内のすべてのドキュメントを選択したい/applications/1。私はそれを行うために以下を使用しました（正しいようです）が、エラーがスローされます：

$qb = $this->dm->createQueryBuilder();
$qb->from()->document('Mango\CoreDomainBundle\Document\Page', 'page');

// I want to select the pages which are a child of /applications/1
$qb->where()->child('/applications/1', 'application');

$qb->getQuery()->execute();

これを実行すると、次のエラーがスローされます。

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'n1.id' in 'field list'

これは、データベースに送り返される SQL クエリです。

SELECT 
    n0.id AS n0_id,
    n0.path AS n0_path,
    n0.parent AS n0_parent,
    n0.local_name AS n0_local_name,

    n1.props AS n1_props,

    n1.sort_order AS n1_sort_order
FROM
    phpcr_nodes n0
WHERE
    n0.workspace_name = 'mango'
        AND n0.type IN ('nt:unstructured' , 'rep:root')
        AND (n1.parent = 'applications/1'
        AND (EXTRACTVALUE(n0.props,
            'count(//sv:property[@sv:name="phpcr:class"]/sv:value[text()="Mango\CoreDomainBundle\Document\Page"]) > 0')
        OR EXTRACTVALUE(n0.props,
            'count(//sv:property[@sv:name="phpcr:classparents"]/sv:value[text()="Mango\CoreDomainBundle\Document\Page"]) > 0')))

誰かが私を助けてくれることを願っています！ありがとう！
