orm: set() method don't removes other connections

Hi,

I have problem with set method on relationship ManyHasMany. I have this code

		if($values->salesmen) {
			$this->entity->salesmen->set([$values->salesmen]);
		}

		$this->orm->persistAndFlush($this->entity);

version 2.2@dev

I want set only one entity and others remove but set method behaves same as method add.

Thanks for any help
