@Meta("tapestry.persistence-strategy=client")
Hi,
I am trying to prevent session creation when using forms and in general. I
searched the mailing list but can not explain why the session is still being
created. I use 5.0.18.
Index.tml
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
<body>
<t:form t:id="myform">
<t:label for="cardNumber"/>:
<t:textfield t:id="cardNumber" value="cardNumber" size="20"/>
<input type="submit" value="Submit"/>
</t:form>
<div>${cardNumber}</div>
</body>
</html>
Index.java
@Meta("tapestry.persistence-strategy=client")
public class Index {
@Property
@Persist
private String cardNumber;
}
Even when I remove the @Persist annotation from the cardNumber property, the
session is still being created. Until I remove the Form from the template.
I am monitoring session creation with a class in my same test project:
package bb.test.session;
import java.util.Date;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
public class MyHttpSessionListener implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent se)
{
HttpSession session = se.getSession();
System.out.print(getTime() + " (session) Created:");
System.out.println("ID=" + session.getId() + " MaxInactiveInterval="
+ session.getMaxInactiveInterval());
}
public void sessionDestroyed(HttpSessionEvent se)
{
HttpSession session = se.getSession();
// session has been invalidated and all session data (except Id)is
no longer available
System.out.println(getTime() + " (session) Destroyed:ID=" +
session.getId());
}
private String getTime()
{
return new Date(System.currentTimeMillis()).toString();
}
}
and with
<listener>
<listener-class>bb.test.session.MyHttpSessionListener</listener-class>
</listener>
in my web.xml.
Of course Firefox extension FireCookie is of help.
So, is this a bug?
Regards,
Borut

So, the Form clearly is not inheriting the persistence strategy given by
@Meta annotation on a page class. At
http://tapestry.apache.org/tapestry5/guide/persist.html there is a paragraph
Persistence Search
By default the value for the Persist annotation is the empty string. When
this is true, then the actual strategy to be used is determined by a search
up the component hiearchy.
For each component, the meta-data property tapestry.persistence-strategy is
checked. This can be specified using the
Meta<http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/annotations/Meta.html>annotation.
If the value is non-blank, then that strategy is used. This allows a
component to control the persistence strategy used inside any sub-components
(that don't explicitly use a different strategy).
In any case, if no component provides the meta data, then the ultimate
default, "session", is used.
I guess Form is not affected by this.

in sessionCreated create and dump an exception and check the stacktrace
to find who's responsible

Try providing a custom validation tracker to form.
Form creates one that is stored in the session by default.
I suspect this is where your session creation is coming from.
Note that for validation to work properly, you'll have to persist the
tracker in some form.
