Segments not working with file upload

[quote author="CroNiX" date="1338330045"]just send them as hidden form fields[/quote]

Unfortunately that doesn't work when having a <input type="file"> from what I understood (?). Because in the controller I can only access $_FILES and $_POST is empty.

For now I will have to return the uploadId on upload success and update my fields in the database with ajax I guess.
