Update multiple select2

[juniorlira]

Hi, I'm starting to use YII2, but I'm having an error when updating select2.

my controller
`

public function actionUpdate($id)
{
$model = $this->findModel($id);
$alunoModulo = new AlunoModulo();
$alunoModulo = AlunoModulo::find()->where(['id_modulo'=>$id])->All();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['index']);
} else {
return $this->render('update', [
'model' => $model,
'alunoModulo'=> $alunoModulo,
]);
}
}
`

My View:
`

field($alunoModulo, 'id_aluno')->widget(Select2::classname(), [ 'data' => ArrayHelper::map(User::find()->where(['role_id'=>3])->all(),'id','username'), 'language' => 'br', 'options' => ['placeholder' => Yii::t('app', 'Select the student ...'),'multiple' => true,], 'pluginOptions' => [ 'allowClear' => true, ], ]);?>

`

error:
Call to a member function isAttributeRequired() on array

thanks
