When attaching a Zend_Form_Element_File to a Zend_Form, the default decorators are not being rendered (Errors, HtmlTag, Label, etc).

class App_Form_FileTest extends Zend_Form
{
    /**
     * Form initialization
     *
     * @return void
     */
    public function init()
    {

        $this->setAttribs(array(
            'name'  => 'postForm',
            'method' => 'post',
            'enctype' => 'multipart/form-data'
        ));


        $this->addElement(
            'Textarea',
            'postmessage',
            array(
                'value'      => '',
                'label'      => 'Message:',
                'required'  => true,
                'style'    => 'height: 150px; width:400px',
                //'propercase' => true,
            )
        );

        $this->addElement(
            new Zend_Form_Element_File(
                'moviefile',
                array(
                    'label' => 'Attach Movie:',
                    'required' => false,
                    'order' => 20,
                    'destination' => Zend_Registry::get('config')->upload_dir,
                    'validators' => array(
                                 array('Count', false, 1),
                                 array('Size', false, 5242880), // 5 megs
                                 array('Extension', false, 'avi,mpg,mpeg,flv,png')
                            )
                )
            )
        );
    }
}
