Yii Crud generates ErrorException out of the box - php

Question

My problem is similar (or identical ?) to this one. However, the solution offered there does not help me.
I used Gii tot generate a model (Guest) with a search model (GuestQuery). Then I used Gii to generate CRUD for these models. Gii generates the code successfully.
Then, a call to /guest/index results in the following error:
PHP Warning – yii\base\ErrorException

7. app\controllers\GuestController::actionIndex()
It looks like php get_called_class() returns a string 'app\models\generated\Guest' That would be correct. Next, YiiBase wants to threat this string as an array. Which results in the above error.
How do I get this working?
I am running Yii 2.0.8 on php 7.0.6.
update: the models and controllers are as generated by Gii:
Guest.php

];
}

public function attributeLabels()
{
return [
