I have an EO with a not null constraint on a date columnn. I have a

It is throwing an exception and claiming that the date field is null
Does the model allow null for this attribute? Did you change the
model after creating the database?
and violates the not null constraint. I don't have anyplace in the
interface that is wired to the date column in question (it is the
insertion date).
I guess I could just set the EO to accept nulls but I thought I
would try to understand why the saveChanges() is trying to update
the row with a null.
You are doing something wrong, either in your model or in your code
(or, I guess, in both). This is the first thing to check:
