Role is NullPage although present

[owzim]

I successfully created a role with the API:

$role = new Role();
$role->name = 'some-role';
$role->save();

It's now there under access/roles/
 
But when I want to get the role via API, I get a NullPage:

$roles->get('some-role');
// or
$this->roles->get('some-role');

Please help!

I was trying to prevent a new creation of the role via:

if(!$role = $this->roles->get('some-role')) {
	$role = new Role();
	$role->name = 'some-role';
	$role->save();
}

But $this->roles->get returns a NullPage instead of null. $this->fieldgroups->get, $this->templates->get and $this->fields->get return null when not present.

So in this case:

$role = $this->roles->get('some-role');
if(!$role || $role instanceof NullPage) {
	$role = new Role();
	$role->name = 'some-role';
	$role->save();
}

fixed it.

I think all collection like classes should either return null or NullPage and not mixed results, right?
