I made a error in OneToMany association and received a notice when persist entity:
Undefined index: ItemEntities
File: /opt/project/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/Entity/BasicEntityPersister.php
Line: 1768

OwnerEntity.php

<?php 
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 */
class OwnerEntity 
{
    /**
     * @ORM\OneToMany(targetEntity="ItemEntity" mappedBy="itemEntities", cascade={"persist"})
     *
     * @var ItemEntity[]|ArrayCollection
     */
    private $itemEntities;
}

ItemEntity.php

<?php 
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 */
class ItemEntity 
{
    /**
     * @ORM\ManyToOne(targetEntity="OwnerEntity", inversedBy="itemEntities")
     *
     * @var OwnerEntity
     */
    protected $ownerEntity;
}

I got this error only with persist.

As the title says:

It is up to you to make sure the property is set for OwnerEntity#$itemEntities: the ORM merely attempts to store what you provided to it.

Also, note that the OneToMany side is never the owning side of the association.
