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.

> 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.

> (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.
>
