[Flow] Re: Removing an object, that has references, leads to "Exception thrown without a stack frame in Unknow

[Christian Eßl]

If someone's interested: I found the problem in my model.

In my case, i mapped $subpages by "page", but if you look at the propertys of my model closely, it was supposed to be mapped by "parent", because thats the name of the ManyToOne-propery $page. Because of that, Doctrine had problems constructing the object tree and threw these obscure errors.

    /**
     * The subpages of this page
     *
     * @var \Doctrine\Common\Collections\Collection<\Test\CMS\Domain\Model\Page>
     * @ORM\OneToMany(mappedBy="page", cascade={"all"}, orphanRemoval=true)
     * @ORM\OrderBy({"date" = "DESC"})
     */
    protected $subpages;
