[Symfony2] Form + oneToMany + EntityType; cascade not working

[Ruben de Vries]

I've been going at this problem for hours now so I figured I better
just ask for help to avoid my head exploding soon ...

I'll paste some snippets and then try to explain.

yaml mapping for doctrime ORM

GoGreat\DemoBundle\Entity\DemoUser:
oneToMany:
comments:
targetEntity: DemoComment
mappedBy: author
cascade: ["persist"]

GoGreat\DemoBundle\Entity\DemoComment:
manyToOne:
author:
targetEntity: DemoUser
inversedBy: comments

DemoUser entity

class GoGreat\DemoBundle\Entity\DemoUser {

public function addComments($comments)
{
$comments->setAuthor($this);
$this->comments[] = $comments;
}
}

DemoUserType form

class GoGreat\DemoBundle\Form\DemoUserType {
public function buildForm(FormBuilder $builder, array $options)
{
$builder->add('name', 'text');
$builder->add('comments', 'entity', array(
'class' => 'GoGreat\DemoBundle\Entity\DemoComment',
'property' => 'body',
'expanded' => true,
'multiple' => true,
));
}
}

this does work

$user = new DemoUser();
$comment = new DemoComment();

$user->addComments($comment);

$em->persist($user);
$em->flush();

this doesn't work

$form = $this->get('form.factory')->create(new DemoUserType());
$request = $this->get('request');
$user = new DemoUser();
$em = $this->get('doctrine.orm.entity_manager');

$form->setData($user);

if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {

foreach ($user->getComments() as $comment) {
var_dump($comment->getBody(), $comment->getAuthor());
}

$em->persist($user);
$em->flush();
}
}


the var_dump just before the persist does throw out the body, but it
doesn't have an author.
I think the form isn't using DemoUser->addComments to set the
comments, but how else could it set the comments?

What am I doing wrong?

If the examples aren't clear enough I can put the demo bundle on
github for you to check ...

Without knowing whether cascade:persist should do the job, i guess it
could be an issue with owning and inverse side of your relation.[1]

"The owning side of a relationship determines the updates to the relationship in the database."

The owning side is your comment (since it is the one with the
inversedBy property), so maybe you should try to save it this way:

$comment->setAuthor($user);

and then look whether it gets persisted.
what i would love to know myself is, how the symfony form framework
handles bidirectional relations like that...

cascade persist works like a charm (check out my '>> this does work'
example) when called stand alone, but it just doesn't work when going
through the form.
because it seems the form API doesn't use the get/set methods to set
the properties o.O?

could be an issue with owning and inverse side of your relation.[1]> "The owning side of a relationship determines the updates to the relationship in the database."
