[Flow] Mapping Problem

[Ali Reza Sajedi]

Dear All,

I have an object called "Kloster" and a OneToMany/ManyToOne association with another object called "Klosterstandort" like:

/**
 * @Flow\Entity
 */
class Kloster {

	/**
     * @var \Doctrine\Common\Collections\Collection<\SUB\Germaniasacra\Domain\Model\Klosterstandort>
     * @ORM\OneToMany(mappedBy="kloster", cascade={"all"}, orphanRemoval=true)
     */
    protected $klosterstandorts

}

/**
 * @Flow\Entity
 */
class Klosterstandort {

	/**
     * @var \SUB\Germaniasacra\Domain\Model\Kloster
     * @ORM\ManyToOne(inversedBy="klosterstandorts")
     */
    protected $kloster;

}

When I try to update an entry I get the following error message:

#1297759968: Exception while property mapping for target type "SUB\Germaniasacra\Domain\Model\Kloster", at property path "klosterstandorts.gruender": Object with identity "Pfarrer Reinhold (1. Dekan)" not found.

The property of the "klosterstandort" which concerns here is called "gruender" (an array):

<f:form.textarea property="klosterstandorts.gruender" value="{klosterstandort.gruender}" />

I appreciate any hint as to what could be the cause.

Thank you.

Ali
