Hi All,
I'm having a weird problem that hopefully someone might have some
thoughts about.
I am trying to auto map and assign more specific constraints to a type
(see User in code below). This is mostly just basic code I've gotten
from blogs. When I run my test, the hbm export file is created and has
the correct attributes. However, the the SchemaExport output to the
console is missing the unique constraint and non-null specification.
The strange part is that is if I use the hbm mappings in the
BuildSessionFactory method (currently commented out) the constraints
are added to the schema. It's when I try to use the auto mapping that
I run into trouble. I also had this working previously (using the non-
fluent configuration, see below) but that code also stopped working
with the same problem when I updated to a recent FNH version.
Is this something that I was doing wrong before and just happened to
work? Or is this a regression?
Thanks!
s.
