Zend File Upload and Element Decorators?

Answer

The File element requires it's own decorator - Zend_Form_Decorator_File.

$this->setElementDecorators(array('File','Errors',
      array(array('data'=>'HtmlTag'), array('tag'=>'td')),
      array('Label', array('tag'=>'th')),
      array(array('row'=>'HtmlTag'), array('tag'=>'tr'))));
