boolean cast in entity and validation error for required, in_list[0,1]

[nowackipawel]

As we know we've got casting in entity class which could cast boolean values to integer (for database) and integers 0,1 to false, true from db.

And I am wondering how to fix that case:

My entity class:

<?php namespace App\Entities\File;

use CodeIgniter\Entity;

class FileConverted extends Entity
{
	protected $fco_id;
	protected $fco_is_active;

	protected $_options = [
		'casts' => [
			'fco_id'			=> 'integer',
			'fco_is_active'		=> 'boolean', //this cast
		],
		'dates'=> ['fco_created_at', 'fco_updated_at'],
		'datamap' => []
	];

and model:

<?php

class FileConvertedModel extends \CodeIgniter\Model
{
	protected $DBGroup 		= DB_ZTN_GROUP;
	protected $table 		= 't_file_converted';
	protected $primaryKey 	= 'fco_id';
	protected $returnType 	= 'App\Entities\File\FileConverted';

	protected $allowedFields = [
		'fco_is_active',
	];

	protected $validationRules 	= [
		'fco_fil_id'				=> 'required|is_natural_no_zero|less_than_equal_to[16777215]',
		'fco_is_active'				=> 'required|in_list[0,1]',
	];
}

and now from other model I am doing sth like this:

$file_converted->fco_fct_identifier = $file_conversion_task->fct_identifier;
$file_converted->fco_is_active = 0;
$file_converted->setConvertedName($file->guessExtension());
$file_converted_model->save($file_converted);

and I've got error:

The fco_is_active field is required.

bacause is_required gets FALSE instead of 0 which I assigned to fco_is_active.

For quick fix we could make new rule like 'valid_boolean', use it at one of the first rules and change $value inside of processRules to false -> 0, true -> 1 for other validation rules like required or in_list[0,1]

What do you think? Is it a bug o proper behavior ?

Or is any way to get casts of saved entity in Rules class methods without passing every cast through Model::save() , Validation::run() and Validation::processRules() ?
