[Flow] Flow 2.2, creating many objects at once, any news?

[mario chiari]

Hi

Say I have a Flow 2.0  application with 1:M models Father/Son, and views
to create or edit a number of Fathers and their Sons at once  (some JS
let a user to add new fields on the fly to the html forms). 

I would like to know if Flow 2.2 let me to simplify my code.

Father : name:string, picture:resource, sons:Collection/son
Son  : father:Father, name:string. 

Setters and getters are as by default but:

public function setSons(\Doctrine\Common\Collections\Collection $sons) {
		foreach ($sons as $son){$son->setFather($this);}
		$this->sons = $sons;

To define a Father createController() which works, it seemed to me that
I need to initialize it as follow:

	/**
         * Initialize the create action
         *
         * @return void
         */
	public function initializeCreateAction() {

$this->arguments['newFathers']
->getPropertyMappingConfiguration()
->forProperty('*')->allowAllProperties()->setTypeConverterOption(
	'TYPO3\Flow\Property\TypeConverter\PersistentObjectConverter',
	\TYPO3\Flow\Property\TypeConverter
\PersistentObjectConverter::CONFIGURATION_CREATION_ALLOWED,		TRUE);

for($i = 0 ; $i < 9 ; $i++){  // use 99 or 999 if you need
	$this->arguments['newFathers']
	->getPropertyMappingConfiguration()
	->forProperty($i.'.sons.*')   
	->allowAllProperties()->setTypeConverterOption(
'TYPO3\Flow\Property\TypeConverter\PersistentObjectConverter',
\TYPO3\Flow\Property\TypeConverter
\PersistentObjectConverter::CONFIGURATION_CREATION_ALLOWED, TRUE ); 
}

$this->arguments['newFathers']
->getPropertyMappingConfiguration()
->setTypeConverterOption('TYPO3\Flow\Property\TypeConverter
\PersistentObjectConverter',\TYPO3\Flow\Property\TypeConverter
\PersistentObjectConverter::CONFIGURATION_CREATION_ALLOWED,TRUE);
 }}

Question is: in Flow 2.2, may I avoid to initializeCreate, or at least
the foreach up to 9, i.e., may I write something like:
forProperty('*.sons.*')?

In my real project, I have suboject of subobject of ..., for several
levels, and I would like to get rid of all the initialize actions. 


Thanks
Cheers
