default value
It's been a year since this post and there are newer versions released.
Is there a solution for this?
If it's not the built-in behavior, I'd like to specify that if the new value is null, then set the value to the default value.
Why else would there be a default value?
I've entered a default, value; I shouldn't need to write a bunch of code for the default value to mean something more than documentation.
