Hi all,
is anybody using Jose Gonzalez's upload plugin [1]?  I have a couple
of open issues regarding its integration inside my web app, but before
filing a bug I wanted to be sure I was doing things the right way.

I attached a couple of validation rules to my Model's attachment
property and they seem to work only while adding a new object to the
database.  If I edit an object, all the rules are processed but they
always return true.

    public $actsAs = array(
                'Upload.Upload' => array(
                        'attachment' => array(
                                'mimetypes' => array(
                                        'application/pdf',
                                )
                        )
                ),
        );

        public $validate = array(
                'attachment' => array(
                        'valid' => array(
                                'rule' => array('isValidMimeType', array(), 
false),
                                'message' => 'File is of an invalid mimetype',
                        ),
                ),
        );

I had a look at the rule code, and on edit operations the function
always exits at its first check:

        public function isValidMimeType(&$model, $check, $mimetypes =
array(), $requireUpload = true) {
                $field = array_pop(array_keys($check));

                if (!empty($check[$field]['remove'])) {
                        return true;
                }

Have you got any idea about this behaviour?  $check[$field]['remove']
in my case gets always initialized to 'M'.  If I comment out the first
check, then the function will always return false (it looks up the
attachment type using $check[$field]['type'] which is still equal to
'M').  It is really strange both lookups return the same string value.


Thanks,
Matteo
