abstract or no
Hi,
Some
tutorials(like:http://www.devshed.com/c/a/Apache/Creating-Your-First-Tapestry-Project/)
uses abstract class for page, while others use a regular class, which one is
better?

Hi Danie,
Thanks for suggeseting T5, after one day learning, somehow I know how to
create a basic T5 app, cool framkework. was reading the book "Enjoying Web
development with Tapestry" before, after several chapters, I found myself
enjoying nothing, with all those diagrams, xml specs, etc.. T5 is really
something enjoyable, you almost like writing a desktop app, if ajax is
added, that will be better than Google's GWT.

If you can wait for AJAX functionality (late 2007?) , I would say go
with Tapestry 5. If you need AJAX immediately, the latest Tapestry 4
is best. Tapestry 5 is the "next generation" Tapestry, and the T4
code is not directly compatible. That said, your T4 code isn't
completely useless either. T5 is still very component based. I've
only worked with Tapestry 4 and 5, and I would say that Tapestry 5 is
easier to learn, although for many people it's been a challenge to get
started initially (mostly due to quickstart directions that weren't
updated, regarding Maven). Also some T5 quickstarts included a few
lines of code that needed to be changed or removed in order for the
code to work. Don't be discouraged if it doesn't all come together at
once -- people who have it running seem to love it, even though it is
not fully completed.
Maven's a great tool, and after you learn the basics I think newcomers
will like it. There is a free ebook on the web that will teach you
more that you'll need to know about Maven.
In Tapestry 5, almost everything you'll need to write is a non
abstract class. The directory structure of your web application is
much better defined, IMHO. One of the best things is that there are
no more xml files for your pages. For me it made things much simpler.
I'm not a Tapestry expert by any means, and I sometimes find myself
wanting to do things the hard way. Luckily there are a lot of nice
people on this list who have politely corrected me, and shown me the
better way.
In addition there is a wiki page for T5 that is actively updated. I'm
only a junior developer, so I try to add simple things that would help
out people like myself. But others add more advanced how-to's. You
might want to take a look, since it also links to sample code included
in Tapestry. From there you can get a feel of how it works.

Hi Daniel,
Thanks for the reply, I'm learning Tapestry 4, from those samples I saw,
it's ok to use either abtract or not as page class, so which one is better?
maybe non abstract class to be compatible with Tapestry 5? I'm just
evaluating frameworks for a coming project, is it advisable to use Tapestry
5 instead of 4? Thanks.

Hi Tapestry 4 relied more on abstract classes. In Tapestry 5, you are
usually writing concrete classes -- tapestry does it's magic on all
the classes under /pages. You can still have an abstract class to
base your pages on, but that class should probably go in /base instead
of /pages, since it wont have a page template of it's own.
I believe this is covered on the Tapestry 5 main website.
