[jira] [Resolved] (WICKET-4729) atmosphere example will stop working if opening the same url in a different tab in the same browser

Emond Papegaaij resolved WICKET-4729.
-------------------------------------

       Resolution: Fixed
    Fix Version/s: 6.1.0

I've reworked the page registration. The BiMap was used to make sure the registration would not grow with every page opened. I've replaced the BiMap with a normal HashMap and added a method to unregister a connection when it is closed.

> If the url of a running atmosphere example is copied and then opened in a different tab while the old one left open in the same browser,
> i.e. there are two atmosphere examples of the same url opened at the same time in a browser, 
> one of them will stop working.
> I found the cause of this problem is that trackingPages in EventBus is using a BiMap.
> If there are different tracking-ids mapping to the same PageKey, one of the map entry will be removed.
> The simple solution would be replacing the BiMap with HashMap, but I think there might be reasons why BiMap is used here.
