DataObject, sequences and validation

Hi, Using DO 1.7.2, I have some code like this using Postgresql as the backend: $dbo = DB_DataObject::factory('sponsor'); $dbo->sequenceKey('sponsorid', true, 'sponsor_sponsorid_seq"); //... set a few field values, but don't touch the sequence ... $sponsorvalid = $dbo->validate(); but this comes back with an invalid value in sponsorid. I don't want to set a value in the field because Postgres is doing that. The field type is a non-null integer and DO thinks that since I have no value there it is invalid. I would like DO to know that having nothing in the sponsorid field is fine. What should I be doing differently? thanks, matt -- Disclaimer: This message (including any attachments) contains confidential information intended for a specific individual and purpose, and is protected by law.
