Did you tried the same with remote views?
I remember that I've encoutered something like this with nulls appended as default values when columns defined in remote view didn't had default values and those columns had NOT NULL constraint in Firebird table. After setting default values for columns, everything was OK.

However when I append data into a cursor attahced to a cursoradapter object the data appears never to be saved in Firebird. I used the same procedure with PostgreSQL and everything worked fine. I simply create the cursoradapter object and execute the Cursorfill method. I get an empty cursor to which I append some data and issue a TableUpdate command. No errors are report when I check with Aerror() but the next time I create the cursoradapter I again get an empty table.
