Any ideas on it?
Yet another question. In my admin application I want to have a link
show client screens. The link must follow to the main site with a
client already signed it (in other words the WebSession, but from
different app is set to hold
chosen client id). What is a way to do it?

Wouldn't it be more powerful to override / hook into the process of

Something like that ...

Hi,
I am using wicket. I have a page with one links which increase the counter
value based on user click on the link, for all these actions I am using Ajax.
For instance user click 5 times on link the counter shows value 5. It is ok but
if I click on browsers refresh button all changes are
store the value on the session? make it a static member variable or store
it at application level? it all depends on what you want: the value to
change independently for each user or be the same for all users...

Hi, I've been using m3 for a while and just tried switching to rc1. I found
several problems:

Why not just return IModel? ?

Yeah, I thought about that. The problem is add() is usually called from

if you are planning on displaying 1000 rows per page, which is quiet
uncommon for webapps, you should produce output as raw html instead of
using listview and adding components inside.

If you want to discard the generated text after rendering, you may use a
