Very good but flawed (Alistair Saldanha)

I passed the Sun Certification for Java in November. This is an excellent book for someone who knows Java and wants to learn JDeveloper. It explains things simply and clearly and got me up to speed on my first database project.I did, however, find two flaws in the book. Try this: run the project on Pages 298/299. Insert a new row. Click on the save button. Now go to the new row you have inserted and make a change in one of the fields. Click on the save button again. You will get an error message. There is a reason why an error is thrown: ROWID is only a partial solution as a primary key, it is inserted at the server level, not by the client. Now if you click the refresh button and then save, it works. The client now has the primary key it needs to update data.The project on Pages 350 to 355 gives an error message even if you do save the data after making a change (and do not make any further changes). It is only supposed to give an error message if you don't save the data after making a change. I haven't been able to figure this one out yet and would love to hear from the authors on a work-around.I've been very impressed with Oracle Press books and I'm surprised these errors slipped through the cracks.
