[FLOW3-general] Self referencing M:N Relation

[Carsten Bleicker]

try something like this?
/**
	 * @var \Doctrine\Common\Collections\Collection<\WS\Rico\Domain\Model\Company>
	 * @ORM\ManyToMany
	 * @ORM\JoinTable(name="ws_rico_domain_model_provider_relations",
	 *      joinColumns={@ORM\JoinColumn(name="parent", referencedColumnName="persistence_object_identifier")},
	 *      inverseJoinColumns={@ORM\JoinColumn(name="child", referencedColumnName="persistence_object_identifier")}
	 *      )
	 */
