The dropDown.ValueMode = "key" has also been an offending line from
the beginning.

The print is:
<biz.ContactBizobj.ContactBizobj (baseclass dabo.biz.dBizobj, id:439330288)>
choices [u'Sr.', u'Sr.\xaa', u'Arq.', u'Arq.\xaa', u'Eng.',
u'Eng.\xaa', u'Dr.', u'Dr.\xaa']
keys [25, 24, 23, 22, 21, 20, 19, 18]
The traceback is the same as before:

If we run your code without the line:
dropDown.ValueMode = "key"
Then there is no exception raise. But, as expected, the value of the
"title_id" field does not get recorded to the db, because it is a
string, not an integer. So there is something wrong with setting
ValueMode.
