py4web virtual fields not included when rows retrieved

[davidmanns]

The documentation says:

A virtual field defined as the one above is automatically computed for all records when the records are selected:

for row in db(db.item).select():
print(row.total_price)

However, this is not happening. Virtual fields are not included in the selected rows. Works as documented in web2py, which is curious as both use pyDAL.
