 * This Component is an extension of the classic Composer used inside the chatter. It is called when a
 * user is just creating a new comment => when we set the id of the Thread to undefined.
 * This enables us to limit the creation of void comments inside the DB and lessen journal entries in
 * it.
 * After comment creation, this component is destroyed and is replaced with the regular Composer.
