[Flow] Exception after validation error

[Winfried Mingst]

I'm looking for hours for a solution. Now I setup a very simple package 
with two models (master, detail, relation 1:1). Master (property name) 
and Detail (properties: detail1, detail2...) should be updateable in one 
form.

The problem is that the dto's  Persistence_Object_Identifiers are 
renewed when updateAction is interrupted by a validation error.
How can I prevent that?


var_dump of $masterAndDetaildto in updateAction when  there is no 
validation error -> works:

\TYPO3\FLOW\var_dump($masterAndDetaildto)

WL\Test\Domain\Dto\Masterdetaildtoprototypeobjectproxy
  master => WL\Test\Domain\Model\Masterprototypepersistableproxy
   Persistence_Object_Identifier => 
'424e9262-f7a2-c3bb-ff4a-d417022f97ee' (36)
   name => 'Hans' (4)
  detail => WL\Test\Domain\Model\Detailprototypepersistableproxy
   Persistence_Object_Identifier => 
'35313225-0ec9-c879-010d-5eefbd627738' (36)
   master => WL\Test\Domain\Model\Masterprototypepersistableproxy
   detail1 => 'Mann' (4)
   detail2 => 'A' (1)
   amount => double 0
-------------------------
var_dump of $masterAndDetaildto in updateAction when there is a 
validation error and after correction updateAction is called again -> 
exception because identifiers are renewed:

\TYPO3\FLOW\var_dump($masterAndDetaildto);

WL\Test\Domain\Dto\Masterdetaildtoprototypeobjectproxy
  master => WL\Test\Domain\Model\Masterprototypepersistableproxy
   Persistence_Object_Identifier => 
'b832029a-9a6a-9aad-f0c5-627d9989bafe' (36)
   name => 'Hans' (4)
  detail => WL\Test\Domain\Model\Detailprototypepersistableproxy
   Persistence_Object_Identifier => 
'b4576ca1-2f0c-3477-7751-702622942cc2' (36)
   master => WL\Test\Domain\Model\Masterprototypepersistableproxy
   detail1 => 'Mann' (3)
   detail2 => 'A' (1)
   amount => double 2
---------------------------
