Problem with ctn list sorters in files box

60 r23500

I have uploaded and unziped attached archive, and added contained files in a files box, from 1999_xxx to 2008_xxx
Then, in container list settings, I have set a descending ordering on "file" field. In edition engine, containers seem to be well sorted (screenshot 1), but when I close the edition engine, containers are bad sorted in my page. If I reopen the edition engine, the containers are ordered same as in page, whereas my descending sorting is still set (screenshot 3)
