[jira] Created: (WICKET-683) Fast multiple clicks cause page
expiration
Fast multiple clicks cause page expiration
------------------------------------------
Key: WICKET-683
URL: https://issues.apache.org/jira/browse/WICKET-683
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.2.6
Environment: linux 2.6.20, firefox 2.0.4, dual core, sun jdk6
Reporter: Ingram Chen
It has been found multiple clicks may cause page expiration. there are known two ways to reproduce such problem:
First:
(1) make a link that require 5 seconds to process.
(2) quick click that link >3 times, after 5 seconds, go to page B
(3) do any thing on page B cause expire.
Mulitple clicks is quite normal under slow network. The user may click link several times because web site is not responsive.
attachement quickstart-click3times.tar.gz is quickstart to reproduce this problem.
(note LeastRecentlyAccessedEvictionStrategy(100) up to 100 access to eliminate eviction issues)
2nd:
step 1: link to homepage
url is http://localhost:8081/quickstart/app
step 2: "double click" link on homepage, go to 2nd instance of page B
url becomes http://localhost:8081/quickstart/app/?wicket:interface=:2::
(double click create two instances of page B)
step 3: use browser back button go back to first instance of page B
url becomes http://localhost:8081/quickstart/app/?wicket:interface=:1 ::
step 4: do anything on first instance of page B will cause expiration.
Ideally 1st instance of page B should in pageMap but it seems got lost.

----------------------------------------
Ok, so at least we pinned down that HttpSessionStore and the kind of pagemaps it uses is the problem.

Eelco Hillenius commented on WICKET-683:
----------------------------------------
One big difference in 1.3 is that we set the SecondLevelCacheSessionStore as the default session, whereas in 1.2 that store didn't exist yet, and we use the HttpSessionStore. You could try to test 1.3 for this problem with the HttpSessionStore by putting this in your application class:
/**
* @see WebApplication#newSessionStore()
*/
@Override
protected ISessionStore newSessionStore() {
return new HttpSessionStore(this);
}
If you can reproduce the problem then, we'll know it has to do with this session store and the page map algorithm it uses.

Ingram Chen commented on WICKET-683:
------------------------------------
I play above two test with 1.3 examples, and it is not reproducible.
Fast multiple clicks won't create multiple instance of target page
( the url remain http://localhost:8081/quickstart/app/?wicket:interface=:1:: even with 3,4...etc clicks )
So this only affects wicket 1.2 branch.
The question is where is the magic in 1.3 ?
We can't upgrade to 1.3 now, but I would like to patch 1.2 by ourself.

------------------------------------
I test 1.3 locally and yes, there is no expiration when using SecondLevelCacheSessionStore.
After switching to HttpSessionStore, the behavior is the same as 1.2.x

Matej Knopp commented on WICKET-683:
------------------------------------
I believe this actually a "feature" of AccessStackPageMap. We've talked about this a lot with johan, and I'm affraid there really is no good solution (apart from using 2nd level cache session store). Anyway, maybe it's time to reconsider the behavior of dropping pages from accessstackpagemap.
