It looks as though your database table has a BEFORE INSERT trigger to
populate the ID field when the database receives NULL for it. Could you
look at the table using IB_WISQL's Browser, and inspect its Triggers page?

If delphi is not giving you an exception on an ID field that you know is
NOT NULL, then have a look at the ID column's REQUIRED attribute in the
Fields Editor. If it is checked off, then your app is allowing the trigger
to do the work.
