How to define a published field as not null?

Hi,

I could not find this in the SAD, but how do I define a field as being not null? To define a field as unique, I would specify
'stored false' when defining a published property.
Someone?

Thanks,

Wai

There is no such feature by now, unless you use a custom validator pattern.

My concern about such a feature is that there is no NULLable value in Delphi (with the exception of the variants).
How could we map those values at Delphi code level???

See the SAD pdf about this point.
