Initial Values Normalizer produces StdClass instead of Array for collections

[Jakub Zawiślak]

Symfony 2.8

I have a form:

$builder->add('name', TextType::class);
$builder->add('contacts', CollectionType::class, [...]);

The normalizer produces this output:

stdClass Object
(
    [name] => Test
    [contacts] => stdClass Object
        (
            [0] => stdClass Object
                (
                    [value] => TestValue
                )
        )
)

instead of:

stdClass Object
(
    [name] => Test
    [contacts] => Array <--------- array
        (
            [0] => stdClass Object
                (
                    [value] => TestValue
                )
        )
)

I'm passing this data to a JS in this way inside <script> in .twig:

window.form.initialValues = {{ initialValues|json_encode|raw }}

stdClass and Array are different in JSON format. stdClass gives {0: item} instead of [item].

As a result I have error while using liform-react in ConnectedFieldArray.js:83

nextValue.every is not a function

When I hardcoded StdClass -> Array conversion, all works

$initialValues->contacts = json_decode(json_encode($initialValues->contacts), true);

Hi @jakub-zawislak ,

I'm having a hard time
I'm trying to implement a collection type, but the output just gives me the first row of the collection.
Any idea what this problem might be?

My output is just this:

{
    "schema": {
        "title": "visaexpress_wizardbundle_wizard",
        "type": "object",
        "properties": {
            "wizard_questions": {
                "type": "array",
                "title": "wizard_questions",
                "items": {
                    "title": "0",
                    "type": "object",
                    "properties": {
                        "question": {
                            "type": "string",
                            "title": "question",
                            "propertyOrder": 1
                        },
                        "helper": {
                            "type": "string",
                            "title": "helper",
                            "widget": "textarea",
                            "propertyOrder": 2
                        }
                    },
                    "required": [
                        "question"
                    ]
                },
                "propertyOrder": 1
            }
        },
        "required": [
            "wizard_questions"
        ]
    }
}

WizardQuestion have 5 rows !
