Steps to reproduce

HouseAdmin.php:

$formMapper

                    ->add('images', 'sonata_type_collection', [], [

                    ])
                ->end()
            ;

ImageAdmin.php:

$formMapper

I have the same problem. In my case the Admin generated that error when the form was done like this:

protected function configureFormFields(FormMapper $formMapper)
...
       if ($this->isCurrentRoute('edit')) {
         $formMapper->add('something', 'sonata_type_collection', 
                        array('required' => false, 'by_reference' => false),
                        array('edit' => 'inline', 'inline' => 'table')
                    );
       }

If its out of the route check, it works..

[OskarStark]

Why does this issue belongs to the Userbundle?

[haivala]

It does not.. I just googled the error and found this

[danielantelo]

@haivala did you ever find a way of using the route check as you showed? I am having the same issue, this is the only thread i found with the exact same problem i am facing. Thanks!

[jordisala1991]

Try updating admin bundle to the latest version, and probably all the other sonata bundles too.

Closing because this does not belong to user-bundle.

                    );
       }

This makes it work if($this->isCurrentRoute('edit') || $this->getRequest()->get('_route') === 'sonata_asadmin_append_form_element'))
