Session creation
Hi,
is there a simple way to detect which part or component of my page
forces Session creation? I do not have @Persist or @ApplicationState in
page class and it still create session.
Thanks
Tomas

Hi again,
I created completely new project: mvn archetype:create
-DarchetypeGroupId=org.apache.tapestry -DarchetypeArtifactId=quickstart
-DgroupId=org.test -DartifactId=web -DpackageName=org.test.web
-Dversion=1.0.0-SNAPSHOT
And changed as says my last email. Complete project is in attachement.
When you run mvn jetty:run and go to http://localhost:8080/web/ you will
see, that it will create session. What is wrong? Normally I create an
issue, but you all says that it works.
>curl -I localhost:8080/web/
HTTP/1.1 200 OK
Expires: Thu, 01 Jan 1970 00:00:00 GMT

Yes restarted. I deleted all from Index, but form. What am I doing

Have you put this annotation in all pages with Form components and
restarted you application (to clear the session)?

Layout's still a component (unless you have a page named Layout), need to be
in the page class. I can verify the meta annotation works ok.

Hmm, I do not know what I'm doing wrong, but it does not work. It still
create session.
@Meta("tapestry.persistence-strategy=client")
public class Layout {
@Component
private Form queryForm;

Put it in the page class at which the Form component is used. I was wrong
when I suggested to put the annotation in the component. I'm sorry.

Thank you,
yes problem is in Form. I do not know how to switch off persistence of
validation so I will use standard <form> tag.
Meta did not work, because I can't use it on component variable. It can
be used only to @Target(TYPE). Maybe you have different version.
Also thanks to Andreas Andreou for Session listener. Great tool to find
out why session is created.

Use httpsessionlistener
http://www.xyzws.com/servletfaq/when-do-i-use-httpsessionlistener/7
In the sessionCreated method, just create an Exception and log it to examine
the traces - or even throw it if you don't want any sessions at all
and want to be
100% sure :)

I wish I knew, but, by default, the Form component uses the session to
store validation info.
Try putting @Meta("tapestry.persistence-strategy=client") in your page
classes or in your components instances. Something like
@Component
@Meta("tapestry.persistence-strategy=client")
private Form form;
