Thanks for your replies. I can confirm the described behavior without
setResponsePage().
I created issue WICKET-5165 for this.

Hi,
Since you are redirecting to another stateless page
(setResponsePage(Class)), the browser is redirected to the new url which
creates a new, temporary session for the second request.
If you don't link to another page (so no setResponsePage call), it will
work, since the response is rendered in the same request cycle as the
request.
Correct!
Wicket needs to make the redirect to change the url in the browser address
bar. And renders the page in the second request ...
So you may be right - org.apache.wicket.Session#addFeedbackMessage() should
bind the session. Or at least write a warning for temporary sessions.
Met vriendelijke groet,
Kind regards,

Hi,
This is not the behavior I'm getting. I created a stateless page with
this:
add(new FencedFeedbackPanel("feedback"**));
add(new StatelessLink<Void>("success") {
@Override
public void onClick() {
getSession().info("Success message (without bind())");
setResponsePage(**SessionMessagePage.class);
}
});
add(new StatelessLink<Void>("**successBind") {
@Override
public void onClick() {
getSession().bind();
getSession().info("Success message (with bind())");
setResponsePage(**SessionMessagePage.class);
}
});
The "success" link does not display a session message in the feedback
panel if the session is temporary. It does work when the session is bound
however.
I stepped inside FenceFeedbackPanel#**newFeedbackMessagesModel() and
compared the Session object returned by getSession() there and in the
"success" link. They are not the same java object.

Hi,
Wicket uses temporary Sessions for stateless application.
Adding a feedback message to such session will live till the end of the
current request. Since the response page is rendered in the same
request/response cycle the feedback messages should be still reachable.

Hello,
When using the Sessions info(), error() and success() methods, and the
session is not bound, the messages are lost. This can happen easily
when on
stateless pages. The fix for this is easy: I need to make sure the
session
is bound and call Session.bind().
However, I think it would be nice for the Session to get bound
automatically when adding messages to it. Otherwise, the messages are
silently discarded and the cause is not so obvious. What do you think,
should I open an issue for this?
