[FLOW3-general] help needed: editing multiple objects in one form

[Wasko]

Hi,

I'm programing a simple app to learn how to create and edit data from
two objects in one form (dto). I did it like in the Cookbook 
http://wiki.typo3.org/FLOW3_Cookbook written.

Creating datasets works fine. But how can I edit them? Calling edit 
action ends up in errors like that:

/wl.test/masterdetail/edit?master[__identity]=123456
Error: Required argument "masterdetaildto" is not set.


/wl.test/masterdetail/edit?masterdetaildto[__identity]=123456
  Exception while property mapping for target type 
"WL\Test\Domain\Dto\Masterdetaildto", at property path "": It is not 
allowed to map property "__identity". You need to use 
$propertyMappingConfiguration->allowProperties('__identity') to enable 
mapping of this property.



Apps's sources can be found here https://github.com/regioadmin/WL.Test

The app has two models called master and detail (1:n)

masterdetailcontroller is for creating and editing :

/Controller/MasterdetailController.php

controller uses this dto:
