After a few tutorials though, D2W ought to be introduced because
it's by far the most useful feature for a beginner.
I totally disagree with that as long as you don't dive into
"Wonder"land. You'll end up with locking applications, miserable
performance, no workflows at all, a look that will was okay in the
90's but not today, and not enough customization to make a customer or
even internal colleagues happy.
And honestly, the assistant ought to be usable for people starting
out.
Definitely not the assistant in its current form. I have some old rule
files here, created by that piece of ... and guess what: they have
thousands of rules for things you can do with a few dozen. Nobody will
ever go through that crap, and clean it up. No way.
Sure, once you've customized things to a certain point for certain
entities the simplistic model used by the assistant is no longer
useful but until then it's great and should not be discounted.
As I said: as it creates "rules from hell", somebody digging in there
will just starting with replacing one page after the other with non-
D2W if he is confronted with the hundreds of rules created by the
assistant. I have a project here with a couple of hundred rules -
spread over 8 different files, I don't dare thinking about how many
rules the assistant would have created for that ...
To go into D2W in a useful way - again, in my opinion - you have to:
- understand how EOF works and how you do all enterprise logic there
- understand prototypes so you write rules that use the prototype to
"know" what component to use
- understand how to read and dig through the components to see how
they work
- get your brain wrapped around the rule system - low level, to really
understand the power
If the tutorial can provide that: perfect. I'd be happy to see more
people out there using D2W. How many are there really?
And another thing: the days, when you could come up with a standard
D2W look & feel application are over. Users want Ajax, they want "Web
2.0 feeling", they want a cleaner interface - you can't provide that
without understanding how it works - and you don't when you don't have
the WO understanding to build on. Maybe one day Apple will create a
more usable D2W look, but right now, hmmm, I wouldn't want to use the
existing ones. They just are not good / powerful enough.
