Setting not-nullable field to null - nothing happens

Hi everyone,

I'm struggling to understand something here and am wondering if it's a *feature* of WO/EOF.

I have an entity called "Category" with a not-nullable "name" String field. When I create a new one and forget to set a "name"
I get a ValidationException that says "Please provide a Name" and I spit the user back to the same page (good).


If I have an existing Category with a valid name, and I try to set the name to null, the setter on the entity is never called (I have logging in there) there is no validation and no SQL is generated.
The object just remains with it's old name the user moves off to something else. It is as if they never tried to change it to null.
I would much rather a ValidationException be raised so I can hold up there user and say "Please provide a Name" to make it clear that what they were trying to do did not work.


Is it a "feature" of WO/EOF that it won't let you set a not-nullable to null? Is there any way I can override this behavior?

WO 5.4.3 on 10.5.6

Thanks very much,
