ArrayHelper::map and array query results

[neoacevedo]

Is it my impression or the method map of ArrayHelper isn't working as is expected?

For instance, if I have this query:

// ActiveRecord attributes: id, firstName
$arrayResults = MyModel::find()->where(['status' => MyModel::STATUS_ACTIVE)-->orderBy(['firstName' => SORT_ASC, 'lastName' => SORT_ASC])->asArray()->cache()->all();

Using map method:

$mapArray = ArrayHelper::map($arrayResults, 'id', 'firstName');

It will return an empty array instead the key->value asociation where the key should be the value for 'id' and the value should be the value for 'firstName'.

But if I dump the $arrayResults and use the raw array, it will work.

I found my bug, I was using a magic property and the array in the query results doesn't have it.
