Hey Claus,
you are, as always, correct!
The reason why this trick worked on images for me before is that I did
explode on them and returned them as array.
I modified the getter, following your advice, to this and it works:
public function getTypes() {
return $this->types->toArray();
}
Thank you!
Dmitri.
