Hi, I'm having a 'EmailFolder' entity and trying to delete all mail folders like this:

$folders = $entityManager->getRepository('Application\Entity\EmailFolder')
                ->findBy(array('user'=>$user));
foreach ($folders as $emailFolder) {            
            $entityManager->remove($emailFolder);
            $entityManager->flush();
}

This raises an InvalidArgumentException exception:

 Doctrine\ORM\ORMInvalidArgumentException
 A new entity was found through the relationship 'Application\Entity\EmailFolder#parentFolder' that was not configured to cascade persist operations for entity: Application\Entity\EmailFolder@0000000068c39bba0000000018303d0f. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist  this association in the mapping for example @ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'Application\Entity\EmailFolder#__toString()' to get a clue.

But, when I delete the entities as follows, no exception is raised:

foreach ($folders as $emailFolder) {            
     $entityManager->remove($emailFolder);    
}        
$entityManager->flush();

What's the difference? Why in the first case there is an exception, but in the second one there is no exception?

Here is the code of the entity:

<?php
namespace Application\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Application\Entity\EmailAddress;

/**

    protected $parentFolder;

    public function __construct() 
    {
    }

    /**

     */
    public function getId() 
    {
        return $this->id;
    }

    public function getFolderId() 
    {
        return $this->folderId;
    }

    public function setFolderId($folderId) 
    {
        $this->folderId = $folderId;
    }

    public function getParentFolder() 
    {
        return $this->parentFolder;
    }

    public function setParentFolder($parentFolder) 
    {
        $this->parentFolder = $parentFolder;
    }

    public function getName() 
    {
        return $this->name;
    }

    public function setName($name) 
    {
        $this->name = $name;
    }

    public function getUser() 
    {
        return $this->user;
    }

    public function setUser($user) 
    {
        $this->user = $user;
    }

    public function getDeltaLink() 
    {
        return $this->deltaLink;
    }

    public function setDeltaLink($deltaLink) 
    {
        $this->deltaLink = $deltaLink;
    }

    public function getLastSynchronized() 
    {
        return $this->lastSynchronized;
    }

    public function setLastSynchronized($lastSynchronized)
    {
        $this->lastSynchronized = $lastSynchronized;
    }
}
