Ok, I got your point.. It's ok to reference pages from one another but
I'd rather focus on attaching/detaching and the amount of data I keep in
my models.. Thanks very much for the clarification..

Passing a Page instance to the constructor of another Page doesn't sound
right to me. Again, it depends on what you're trying to do, but I haven't
seen many instances where passing an instance of 'Page a' versus an IModel
with the data 'Page a' is displaying is the 'right' thing to do (in my
opinion).
actually passing a page into another page for a back reference is
perfectly suitable. as usual the thing to watch for is that you
properly use detachable models.

So basically if it's worth it for you to grow the session size on the app
server to avoid the overhead of re-querying it from the database, go
crazy... but I don't think the UI framework is the best place to handle data
caching.

Hi all,
I'm quite new to Wicket and I'd like to ask whether what I'm doing is
right. Say I have two pages A and B. Page A loads a list of information
from the database and keeps it in an instance field. When a link on page
A is clicked, a new page B is created and page A passes itself as one of
the constructor arguments of B. Page B displays the information and
includes a link at the bottom saying "Back". When this link is clicked,
Page B calls setResponsePage() using the instance of Page A that was
passed in its constructor, and Page A is displayed again.
That way I believe that I avoid reloading the data from the database
again in Page A.
But I think somewhere in the mail archives I've read that it's
recommended to use setResponsePage(Class) instead of using
setResponsePage(Page). So I'm wondering whether I'm doing it right, and
if there is a better way I'd like to learn it.
Sorry if this is a dumb question but I want to be confident about what
I'm developing..
Regards,
SerkanC
