The only thing I can say about that: Don't make beginners miserable
with D2W. To use D2W and to be able to customize an application to
your needs, you need a way more deep understanding of WebObjects than
a tutorial can provide.
And personally I think that your tutorial is way overfilled with
stuff. Beginners can take only so much in a tutorial. If you don't
want to write a 600 page book, you will not be able to bring all that
stuff in, add diagrams and screenshots and explain everything a
beginner needs to know. And believe me: I know what I'm talking about
as I'm facing the same problem.
That tutorial is nearly finished, so I am starting with the
DirectToWeb part. On Leopard, the DirectToWeb Assistant does not work.
If you really want to use D2W - stay away from that rule-breaking,
stupid assistant. Nobody will ever understand D2W in the necessary way
with seeing and writing actual rules. In my opinion that assistant was
a bad idea from the very beginning. And I do a lot of D2W.
(and no, Rule Editor is not an easy and quick tool if you're a
beginner and you don't want to shoot yourself in the foot)
Again: D2W is WAY OVER THE HEAD for a beginner to be happy with. It is
a very cool technology demonstration and it is an incredibly powerful
tool for WO developers who really understand WO but it is also
something where beginners will hit the wall with the first
customization they want to make.
