I have a selection field in a custom module:

'firmFlagDescr': fields.selection([(1, u'ΕΠΙΤΗΔΕΥΜΑΤΙΑΣ'), (0, u'ΜΗ ΕΠΙΤΗΔΕΥΜΑΤΙΑΣ'), (2, u'ΠΡΩΗΝ ΕΠΙΤΗΔΕΥΜΑΤΙΑΣ')], u'Κατάσταση')

It shows up fine in UI as a drop down box with all 3 options.

The problem is however that whatever change I make in the selection, it is not saved (either through clicking save via UI or changing value from python code).

Any pointers?
