serialize_null setting without effect for arrays containing NULL values?

[mgrobelin]

Hello,

I'm using fos_rest & jms_serializer bundles to have some joy while building an api with symfony.

Depending on the setting fos_rest.serializer.serialize_null = (true|false) this structure...

$result = array();
$result["data"] = array(0, 1, NULL);
$result["more_data"] = NULL

... is going to be jsonized ...

/* fos_rest.serializer.serialize_null = true */
/* where is 3rd value in data ???? */
{
  "data": [
    0,
    1
  ],
  "more_data": null
}

... or ...

/* fos_rest.serializer.serialize_null = false */
{
  "data": [
    0,
    1
  ]
}
}

How comes null values in an array are removed from serialized result?

The controller code I'm using right now is this:

$result = array();
$result["data"] = array(0, 1, NULL);
$result["more_data"] = null;

$serialization_groups = array("public", "me");

$context = new SerializationContext();
$context->setGroups($serialization_groups);

$view = FOSView::create()
        ->setData($result)
        ->setSerializationContext($context);   
return $this->get('fos_rest.view_handler')->handle($view);
