thank you very much for your code snippet...
it's indeed simpler than i imagined :)
do you think this issue is worth a jira ticket?

>i could imagine to provide a decorator for the ASOManager
A decorator would be better than my solution, but the same result: I
simply use a singleton service to sign out users, and attach a dependancy
to the ApplicationStateManager, the following method is the relevant
portion of the code that you could use in your decorator:
/**
* explicitly destroy all tapestry ASO's on
* logout as a safeguard, only leaving {...@link
UserSecurityManager} in tact
*/
@SuppressWarnings("unchecked")
private void destroySession() {
Enumeration sessionAttributes =
getSession().getAttributeNames();
try {
while
(sessionAttributes.hasMoreElements()) {
Class<?>
c = null;
String
element = (String) sessionAttributes.nextElement();
if
(element.startsWith("aso:")) {
element = StringUtils.stripStart(element, "aso:");
c = Class.forName(element);
if (!element.equals(UserSecurityManager.class.getName()))
asm_.set(c, null);
}
}
} catch (ClassNotFoundException e) {
Logger.getLogger(getClass()).error(
"An ASO Class was not resolved when trying to remove it from state: "
+ e.getLocalizedMessage());
}
}
Just two quick notes:
1. Class.forName("The String canonical class name arg") is my preferred
way to get at the class and avoid any potential classloader issues
2. The line: if (!element.equals(UserSecurityManager.class.getName())) is
left alone as I have a requirement not to touch this class, I have simply
left it in in case you have a
similar issue.
regards,
Peter

IllegalStateException
hi peter,
can you share your code. i really don't see a quick fix :)
i could imagine to provide a decorator for the ASOManager
or for the SessionApplicationStatePersistenceStrategy
and store all the objects/fields in an custom wrapper object that
in turn is saved in the HTTPSession. which i then could control
and clear whenever i need it.

Re: Tapestry 5.0.18 -> 5.1.0.5 Upgrade: Session IllegalStateException
Hi Kristian,
I experienced similar problems between Tapestry versions (5.0.18 and 5.1)
with exactly the same use case, I never took the time to dig more deeply
though as I simply had to find a quick fix, which was to destroy / remove
all ASO's explicitly... not elegant but efficient, and have had no
problems since. I will glad to share the code if you can't find a
workaround.
Cheers,
Peter

IllegalStateException
i already use the Tapestry Request service. But the RequestImpl
wont create a new HttpSession even i tell it ;)
i think it is a bug. maybe someone can take a look at it to verify it.
the code and the problem:
if the session has been set once it will never be cleared, thus
ignoring the create parameter. and with create=true i will always
get the old invalidated session.
RequestImpl:
public Session getSession(boolean create)
{
if (session == null)
{
HttpSession hsession = request.getSession(create);
if (hsession != null)
{
session = new SessionImpl(hsession, analyzer);
}
}
if (!create && session != null && session.isInvalidated()) return null;
return session;
}

You should invalidate the session from the (injected) Request object
(not the HTTPServletRequest). This does the necessary bookkeeping.
Kind regards,
Joachim
