[TYPO3-mvc] Tx_Extbase_Persistence_ObjectStorage as Action-Parameter

[Stefan Frömken]

Hello MVC-List,

is there a possibility to do something like this?

/**
  * @param 
Tx_Extbase_Persistence_ObjectStorage<Tx_KeZr_Domain_Model_Invoice>
  * @return string The merged PDF files as ZIP/GZ
  */
public function pdfAction(Tx_Extbase_Persistence_ObjectStorage $invoices) {
	t3lib_utility_Debug::debug($invoices->toArray(), 'objStorage');
	...
}
