I've worked a litle more on this problem.

It seams that utf8 encoding doens't work correct. The select fields and fields i'm working in are in greek. It looks like it doen't recognize the options in selectfields and the content in fields are transmited with strange chars in them.

try with this options below in the test provided by you and you will see.

option 1 - Δεν Εχει

option 2 - Μ/Τ Μηχανικό κιβώτιο

option 3 - Α/Τ Αυτόματο κιβώτιο

Another strange thing is that before it worned when I tryed to select an option that didn't existed in the select feiled. Now it doesn't.
