Error creating or updating model

[ettolo]

Hi OmgDef, thank you for this usefull extension!
I've used in another project (same version) and everything is fine.
In the new project i can't get it work, i get this error:
Getting unknown property: common\models\Calibers::description, notes

description and notes are fields in the calibersLang table.
The Calibers model is the following:

namespace common\models;

use Yii;

use omgdef\multilingual\MultilingualBehavior;
use omgdef\multilingual\MultilingualQuery;

/**
 * This is the model class for table "calibers".
 *
 * @property integer $id
 * @property string $inch_diam
 * @property string $mm_diam
 * @property integer $sort
 * 
 * @property CalibersLang[] $calibersLangs
 */
class Calibers extends \yii\db\ActiveRecord
{

    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'calibers';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['inch_diam', 'mm_diam'], 'required'],
            [['sort'], 'integer'],
            [['inch_diam', 'mm_diam'], 'string', 'max' => 255],
            [['description', 'notes'], 'required'],
            [['description, notes'], 'string', 'max' => 255],             
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'id' => Yii::t('cartucios', 'ID'),
            'inch_diam' => Yii::t('cartucios', 'Diameter in inches'),
            'mm_diam' => Yii::t('cartucios', 'Diameter in mm'),
            'sort' => Yii::t('cartucios', 'Sort'),
            'description' => Yii::t('cartucios', 'Description [ITA]'),
            'description_en' => Yii::t('cartucios', 'Description [EN]'),
            'notes' => Yii::t('cartucios', 'Notes [ITA]'),
            'notes_en' => Yii::t('cartucios', 'Notes [EN]'),
            
        ];
    }

    /**
     * @return \yii\db\ActiveQuery
     */
    public function getCalibersLangs()
    {
        return $this->hasMany(CalibersLang::className(), ['calibers_id' => 'id']);
    }
    
    
    public function behaviors()
    {
        return [
            
            'ml' => [
                'class' => MultilingualBehavior::className(),
                'languages' => [
                    'it' => 'Italiano',
                    'en' => 'English',
                ],
                //'languageField' => 'language',
                //'localizedPrefix' => '',
                //'requireTranslations' => 'false',
                //'dynamicLangClass' => 'true',
                //'langClassName' => CalibersLang::className(), // or namespace/for/a/class/PostLang
                'defaultLanguage' => 'it',
                'langForeignKey' => 'calibers_id',
                'tableName' => "calibersLang",
                'attributes' => [
                    'description', 'notes',
                ]
            ],
        ];
    }
    
    public static function find()
    {
        return new MultilingualQuery(get_called_class());
    }
    
}

If i remove description and notes from validation rules then i get no error but fields are not saved in the table.
Like in the working project i made, i've not created the calibersLang class
Any idea?
Thanks in advance!
Best regards,
Nicola

Hi @ettolo! It was a mistake in your validation rule [['description, notes'], 'string', 'max' => 255]
