Hi,
The following works
db=DAL('sqlite:memory')
db.define_table('tt',
Field('vv', 'integer'),
Field.Virtual('x', lambda row: row.tt.vv * 10))
db.tt.insert(vv='1')
print db(db.tt).select().first()
printing
<Row {'x': 10L, 'id': 1L, 'vv': 1L}>
We need more details to understand what is failing in your case. Can you
post a failing example?
