Hi!
Another option is to create the object using BXDatabaseContext's  
method -createObjectForEntity:withFieldValues:error: and pass the  
required value. If you want to create the object using  
BXSynchronizedArrayController, a default value is needed, since NOT  
NULL constraint can't be deferred.
