[Texo] Annotation to set EAttribute for no-NULL [message #1705605]

How do I set a texo annotation for an EAttribute such that the db will refuse to accept NULL values for the column? The db (and presumably hibernate layer) allow a column/EAttribute to be null by default. I want to set a specific EAttribute/column to not accept null values ever.

I've looked over the options when editing my .annotationsmodel but can't seem to find something that matches the above.

Any help would be most appreciated!

Hi Mike,
You can use a Basic or Column annotation in the annotations model.
http://stackoverflow.com/questions/5602908/jpa-which-should-i-use-basicoptional-or-columnnullable

I would use Basic annotation for this.
