Tapestry 5.0.18 -> 5.1.0.5 Upgrade: Session IllegalStateException

hi,

using 5.0.18 it was able to invalidate a HttpSession (via the Request) 
and then to create a new one to store a new object (subject).

in 5.1.0.5 this changed because the Request will always cache the old
Tapestry Session object and not attempt to create a new Http Session
as long as the reference is not null although it is invalidated.

Are there any workarounds? Why i'm doing this: if you're logged in
as XXX you can re-login as YYY if you want and have a new https 
session.

g,
kris

used to work
public void setSubject(Subject subject)
{
   Session session = request.getSession(false);
 
   // create a new session
   if (session != null && !session.isInvalidated())
   {
        session.invalidate();
   }
   request.getSession(true);

   asoManager.set(Subject.class, subject);
}

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

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.

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

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)

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