[Flow] Dynamically add element to array collection with fluid form

[Christian Loock]

Hi,

this is how I did it:

     public function initializeUpdateAction()
     {
         $databaseServerMappingConfiguration = 
$this->arguments->getArgument('databaseServer')->getPropertyMappingConfiguration();
         /* @var $commentConfiguration 
\TYPO3\Flow\Property\PropertyMappingConfiguration */
$databaseServerMappingConfiguration->forProperty('databaseUsers')->allowAllProperties();
         $databaseServer = $this->request->getArgument('databaseServer');
         $databaseUsers = $databaseServer['databaseUsers'];
         // \TYPO3\Flow\var_dump($databaseUsers);
         foreach ($databaseUsers as $key => $databaseUser) {
$databaseServerMappingConfiguration->forProperty('databaseUsers.' . 
$key)->allowAllProperties();

$databaseServerMappingConfiguration->allowCreationForSubProperty('databaseUsers.' 
. $key);
$databaseServerMappingConfiguration->allowModificationForSubProperty('databaseUsers.' 
. $key);
         }

     }


It works without exceptions, and the database users get created. 
However, they dont have the reference to the databaseServer set :(
