TYPO3 Core

Only relevant for TYPO3 7.3.0

If you are using an extensions together with extbase with parent and children records (e.g. with IRRE), it's no more possible to use bedirectional relations.

This worked like a charm in the past:

parent model

    /**
     * childrens
     *
     * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Vendor\Ext\Domain\Model\Children>
     */
    protected $childrens;

children model

    /**
     * parent
     *
     * @var \Vendor\Ext\Domain\Model\Parent
     */
    protected $parent;

With 7.3 a nesting level error comes up.
Is this a bug or are you aware of this behaviour?
