It's not supposed to work that way. Only values that were changed
after the new record was created are supposed to be passed; the
"blank" values are supposed to be ignored.
The reason for the blanks is that a record in Python is a dict, with
column names as the keys. There is no way to have a key without a
value, and in order to be able to be edited with UI controls, we need
to supply a value of the same type as the column.
I think that the way it should work for new, unsaved records is as
follows:
modified: used to determine isChanged(), and included in INSERT.
default: not used to determine isChanged(), but included in INSERT.
blanks: not used to determine isChanged(), and not included in INSERT.
This will take some additional work, so I thought I'd run this
delineation by everyone first. If this sounds good, we can take the
discussion over to dabo-dev.
