[TYPO3-mvc] Fluid: form.select view helper and empty default item

[Laurent Foulloy]

Hi all,

I have implemented a solution about which I would like your advice:

1) A class which extends Tx_Extbase_MVC_Controller_Arguments to overload 
the method createArgument().
2) A class which extends Tx_Extbase_MVC_Controller_Argument to overload 
the method initializeObject(). This class is instanciated in the 
previous createArgument() method.
3) A class which extends Tx_Extbase_Property_Mapper to overload the 
method transformToObject(). This class is instanciated in the previous 
initializeObject() method.
A slight modification is introduced in transformToObject(). The 
instruction unset($propertyValue['__identity']); is replaced by

if ($propertyValue['__identity'] == 0) {
   $propertyTagsValues = 
$this->reflectionService->getPropertyTagsValues($targetType, 'uid');
   if (in_array('AllowUidToBeEqualsToZero', $propertyTagsValues['param'])) {
     $propertyValue = 0;
   }
} else {
  unset($propertyValue['__identity']);
}
It uses the reflection service to check if the uid has an 
"AllowUidToBeEqualsToZero" param attribute.
4) The method initializeObjects() is overloaded in the controller. It 
instanciates the previous class.

To use this feature, in the model associated with the foreign table the 
uid variable must be explicitely defined with a @param as follows :

/**
  * @var int The uid
  * @param AllowUidToBeEqualsToZero
  */
  protected $uid;

Regards

Laurent
