[TYPO3-mvc] Use of an object as argument in a view helper in Fluid

[Florian Rival]

Hi Glenn,

Did you use the DocComment (@param, @return, ...) in order to tell 
extbase the type of parameter you give to the ViewHelper ?

Like this :

   /**
   * @param \Vendor\Ext\Class $object
   * @param string $param
   * @return boolean
   */
public function render($object, $param) {
