I like the summary by Johan much more. Specifically the page should
mention:
- Wicket Pages are just normal Java objects
- Links allow one to move from one Page to another. There are two ways
to do this:
1) Construct a Page like any normal Java object and pass it into the Link.
2) Pass in the Page class and use Link's built-in mechanisms for lazy
page construction. These assume that bookmarkable pages have a
PageParameters constructor and non-bookmarkable pages have a default
constructor.
- We absolutely should have sample code in this page (like Johan
provided) so it is clearer what we're talking about. You can copy/paste
this directly from his email.
Finally, we need to make it clear in this wiki page what happens if you
have a bookmarkable page that is missing a PageParameters constructor
and query arguments are passed in. Does this result in a runtime error?
In fact, I suggest we disallow users to provide a default constructor
for bookmarkable pages. They should *always* provide a PageParameters
constructor. I also found the existing documentation confusing because
it said they may have either a default constructor or a PageParameters
one and I was left asking... "but why?! What's the difference between
the two constructors? when is each called?" We should just simplify it
into a single constructor.
Thank you,

On this topic... can someone *please* post a page in the Wicket
Wiki about Bookmarkable Pages vs normal Pages? Something similar to
our "all about Models" page?
I absolutely lost here. I keep on getting lost on this exact same
topic every couple of weeks and I can't find any decent documentation
on it.
Specifically, what differentiates a bookmarkable page from a
normal one? Why does a bookmarkable page take one constructor with
PageParameters and one without? Which constructor is called if you hit
the URL of a bookmarkable page with and without query arguments? How
do you pass arguments to a non-bookmarkable page if its constructor
does not take a PageParameters argument?
I would really appreciate this as it's rather basic stuff and I'm
totally lost on it. I wish you guys had some sort of irc channel or
something we could discuss things on because often I have really
simple questions I would appreciate help with and there is just
nowhere to ask (chat vs mailing list yield different results).
Thanks,
Gili
