Yii2: Error message not showing with tabular input, css class 'has-error' is missing

What steps will reproduce the problem?

In the controller, I'm using loadMultiple and validateMultiple to validate several models of the same class.

In the view where I render the form, I have this (as explained in the doc):

<?php foreach ($addresses as $index => $address) { ?>
    <?=
    $form->field($address, "[$index]emailAddress")
    ->textInput(['placeholder' => Yii::t('label', "Enter email address")])
    ->label(false);
    ?>
<?php } ?>

What is the expected result?

If one of the models doesn't validate (server-side), an error message should be displayed.

What do you get instead?

The error message is not showing, because the class "has-error" is missing.
If I name the attribute "emailAddress" instead of "[$index]emailAddress", it works as expected.
