Jira issue originally created by user ablock:

Given the following entities:

namespace Entities;

class Parent {
    /****
     * @OneToMany(targetEntity="Child", mappedBy="parent", cascade={"persist"})
     */
    private $children;
}

class Child {
    /****
     * @ManyToOne(targetEntity="Parent", cascade={"persist"})
     * @JoinColumn(name="parent_id", referencedColumnName="id")
     */
    private $parent;
}

And the following code:

$p = new Parent;
$em->persist($org);
$em->flush();

$c = new Child;
// This method maintains the bidirectional relationship on the application side
$p->addChild($c);

$em->clear();
$id = $p->getId();

$org = $em->find('Entities\Parent', $id);
echo count($c->getChildren());

Should output "1" but instead outputs "0"

Comment created by @beberlei:

cascade-persists are executed when persist() is called, in your case before you add the children. The test-case shows how the behaviour works:

    public function testSavesAOneToManyAssociationWithCascadeSaveSet() {
        $this->product->addFeature($this->firstFeature);
        $this->product->addFeature($this->secondFeature);
        $this->_em->persist($this->product);
        $this->_em->flush();

        $this->assertFeatureForeignKeyIs($this->product->getId(), $this->firstFeature);
        $this->assertFeatureForeignKeyIs($this->product->getId(), $this->secondFeature);
    }

You have to add the children before calling persist.
