I am reading the MEAP version, it is really great, I am sure it needs some more diting but that doesn't bother me. The only thing that I hope to see in final version, is when there are sentences like the following in the book:

"If Image would be an entity class that supports shared references, you'd need more code in your application for the same operations,
as you will see later." . it would be very nice to point a section or page number when that point will be covered later.

thanks for the great book.

Without exception, and we took great care about this, if a sentence says "you will see later" without a reference, it means in a page or two. If it is somewhere else in the book, there is always a chapter/section reference.
