If use upload multifile (eg 3) and upload only "file_2" and set option "ignoreNoFile => true", after validate "file_1" for files "file_2", "file_3" etc, other validators be ignored.

Reproduction:

$this -> setMethod('post');

$this -> setAttrib('enctype', 'multipart/form-data');

// Images elements $element = new Zend_Form_Element_File('file');

$element -> addValidator('Count', false, array( 'min' => 1, 'max' => 3 ));

$element -> addValidator('MimeType', false, 'image/png');

$element -> setDestination( realpath(APPLICATION_PATH . '/../public/uploads/images' ));

$element -> setMultiFile(3) -> setValueDisabled(true);

$this -> addElement( $element );

I fix this in Zend_Validate_File_Upload method isValid, replace "$this->_value = $file;" to "$this->_setValue($file);" for clean "$this->_messages"
