yii2 Multiple model and select2 non-unique id problem - dom

Question

Hi all i'm a noob and i'm tryng to use a multiple model with a select2 in my model i call two time the same table because i write in it two time.
i use a table called "Luoghi" where i write the birthplace and where you live, so i need to use it twice
public function actionView($id)
{
$model = $this->findModel($id);
$ClientiLuoghis = ClientiLuoghi::find()->where(['IDCliente'=>$id])->one();
if (!$ClientiLuoghis) {
throw new NotFoundHttpException("The ClientiLuoghis was not found.");
}
$residenza= Luoghi::find()->where(['ID'=>$ClientiLuoghis->IDLuogo])->one();
if (!$residenza) {
throw new NotFoundHttpException("The residenza was not found.");
}
$lnascita=Luoghi::find()->where(['ID'=>$model->IDLuogoNascita])->one();
if (!$lnascita) {
throw new NotFoundHttpException("The lnascita was not found.");
}
$contatti=contatti::find()->where(['IDCliente'=>$id])->all();
if (!$contatti) {
throw new NotFoundHttpException("The contatti was not found.");
}
$model->Scenario = 'update';
$residenza->Scenario = 'update';
$lnascita->Scenario = 'update';
$contatti->Scenario = 'update';
if($contatti===null) {
throw new CHttpException(404,'The requested page does not exist.');
return $this->render('view', [
'model' => $model,'residenza'=>$residenza,'lnascita'=>$lnascita,'contatti'=>$contatti
]);}
the action works without problems, the trouble is in this
<h3><?= Html::encode('Luogo di Nascita') ?></h3>
<table width="90%">
<tr> <td width="40%"> <?= $form->field($model, 'DataNascita')->widget(DatePicker::classname(), [
'options' => ['placeholder' => 'DataNascita'],
'removeButton' => false,
'pluginOptions' => [
'autoclose' => true,
'format' => 'yyyy-mm-dd'
]
]); ?></TD><td width="5%"><td width="40%"></tr>
<tr> <td width="40%"> <?=
$form->field($lnascita, 'IDComune')->
widget(Select2::classname(), ['data' => $listComnas,
'id' => 'IDcomune',
'options' => ['placeholder' => 'Seleziona Comune ...', ],
'pluginOptions' => [
'allowClear' => true
],
])->label('Comune');
?></td><td width="5%"><td width="40%">
<?= $form->field($lnascita, 'IDProvincia')->
widget(Select2::classname(), ['data' => $listPRnas,
'id' => 'IDProvincia',
'options' => ['placeholder' => 'Seleziona Provincia ...', ],
'pluginOptions' => [
'allowClear' => true
],
])->label('Provincia');
?>
<h3><?= Html::encode('Luogo di Residenza') ?></h3>
<table width="90%">
<tr> <td width="40%"> <?=
$form->field($residenza, 'IDComune')->
widget(Select2::classname(), ['data' => $listComres,
'options' => ['placeholder' => 'Seleziona Comune ...', ],
'pluginOptions' => [
'allowClear' => true
],
])->label('Comune');
?></td><td width="5%"><td width="40%">
<?= $form->field($residenza, 'IDProvincia')->
widget(Select2::classname(), [
'data' => $listPRres,
'options' => ['placeholder' => 'Seleziona Provincia ...', ],
'pluginOptions' => [
'allowClear' => true
],
])->label('Provincia');
?></td> </tr>
the second IDcomune and IDProvincia select2 are empty and blank and i get this advise
[DOM] Found 2 elements with non-unique id #luoghi-indirizzo input#luoghi-indirizzo.form-control input#luoghi-indirizzo.form-control
Any ideas about how to solve?
