FWIW, I find that returning an IPage from a listener method is much
easier than cycle.activate() in most cases....
Cheers,
Paul

That's fine. I just wanted to make sure I don't write any code that is

I think I'm gonna be using the commons configuration library and
read the
page flow from an xml file on application startup. Then, each page
class
would subclass from an abstract page class that would know which
page to
redirect to.
Thanks for your time and input.

Tapestry has no built-in way to set up page flow via an external
file, though I could think of several ways to do it fairly easily.
If you wanted to code it yourself, you could do it by writing a bit
of code to read your table definition, then:
1) Creating a common subclass for all of your pages and include the
"go to next page" feature there, or
2) Put the "look up and go to next page" function in a utility class
and plug it into Hivemind (for Tapestry 4), then...
2a) inject this information into each page, or
2b) intercept (via Hivemind) whatever function you're calling from a
page's form and trigger the redirection to the next page.
There might even be a good place to just stick a class in the request
processing pipeline. Howard could likely tell you.

P.S. Tapestry is rather different from Struts or JSF. I consider that
a feature (as surely many others here do.) You might spend some more
time prototyping with it and then see if you're still hungering for
an external page-flow configuration file.
