Two explanations. One, the transaction is not being committed, in other words
the save is not really happening. Code showing where the save is being done
would be helpful. Two, given that this is Sqlite, you are not connecting to the
database you think you are. Make sure there is not more than one copy of
tutorial.sqlite lying around. It would help to see the code for the bizObj as
well as the connection code.
