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: <?= $form->field($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
