Phalcon\Tag, select multiple - assign defaults from controller

I need to assign several default values to select multiple tag. At the moment, I managed to assign only one value with

$tag->setDefault('element[]', 'value');

If I try to pass array as value, it tells me that only scalar values are allowed. Any way to achieve that?

        $tag = new Select('element[]', array(1,2,3,4,5), array(
            'useEmpty' => false,
            'multiple' => true


Nope, that doesn't works... Here's the code from view:

{{ select("estate_types[]", estate_type, "using": ["id","name"], "useEmpty":false, "multiple":true) }}

And from controller:

$this->tag->setDefault('estate_types[]', array(1,2));

This gives me that:

Phalcon\Tag\Exception: Only scalar values can be assigned to UI components

Solved it via Phalcon\Forms\Element\Select()->setDefault(array())

How to apply it?
