filefield / imagefield do not update

Hello,

i don't know if that is an bug or if I missed something. EditableField does'nt work with filefield/imagefield for me. In an node view the fields are editable if enabled. I can upload an new file or image - in the case of imagefield i do see the image preview in the node. But if I reload the node view, the old image / file does appear. Other fieldtype like 'text' works fine.

Drupal 6.14,
6.x-2.x-dev editablefields (it doesn't work in early versions)

(Sorry for the english. Hope it sounds not to confusing.)

Thanks, for any help.
