SilverStripe dependent dropdown - x is not a valid option

I have a simple dropdown field with 2 values and a dependent dropdown field:

public function areaForm() {
    $datasource = function($val) {
        if ($val =='yes') {
            $areas = DataObject::get('Area', 'ParentID = 0');
            return $areas->map('ID', 'Name');
        }
        if ($val == 'no') {
            return false;
        }
    };

    $fields = new FieldList(
        TextField::create('Name', 'Area Name:'),
        $dropField = DropdownField::create('isChild', 'Is this a sub Area?', array('yes' => 'Yes', 'no'=>'No' ))
            ->setEmptyString('Select one'),
        DependentDropdownField::create('ParentSelect', 'Select Parent Area:', $datasource)
            ->setDepends($dropField)
            ->setEmptyString('Select one')
    );

    return new Form($this, __FUNCTION__, $fields, FieldList::create(new FormAction('doSaveArea', 'Save area')));
}

public function doSaveArea($data, $form) {
    var_dump($data);
    exit;
    $name = $data['Name'];
    $isChild = $data['isChild'];

    if ($isChild === 'no') {
        $area = new Area();
        $area->Name = $name;
        $area->ParentID = 0;
        $area->write();
    }
    elseif ($isChild === 'yes') {
        $area = new Area();
        $area->Name = $name;
        $area->ParentID = $data['ParentSelect'];
        $area->write();
    }
    $this->redirectBack();
}

When ever I try to save my object by submitting the form, it gives me the same message:

Please select a value within the list provided. x is not a valid option

The values are being populated correctly. I can see them in the browser by inspecting the element. Yet if I select ID 1 for example it says "1 is not a valid option" etc for each Area object. It gets stuck at validation, doesn't even go to the action. I've done similar things in other parts of the site/other sites and they work fine.

Why is this validation incorrectly blocking the form submission and how do we fix this?

Seems like you just need to create an Array of your Map object.

if ($val =='yes') {
    $areas = Area::get()->filter('ParentID', '0');
    return $areas->map('ID', 'Name')->toArray();
}

Normally you could just use the Map object as the source for a DropdownField. But I think the DependentDropdownField has a little trouble with the Map object.
