----------------------------

             Summary: ComponentNotFoundException using AbstractAjaxTimerBehavior and different AjaxChanels
                 Key: WICKET-6022
                 URL: https://issues.apache.org/jira/browse/WICKET-6022
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 6.20.0
            Reporter: Paul


I've got the following problem:
I use several Ajax-Channels for my Project. When an AbstractAjaxTimerBehavior is attached to a element which is later removed via Ajax, I get a little later a RuntimeException, as the Timer is still active, but has no Component left attached to the page.

I attached a Quickstart demonstrating this problem. If you leave the AjaxChannel as it is, you won't have the problem, as the timers are stopped upon removal of the component the timer is attached to. But if the name of the channel differs from the default value, this problem occurs.

Cheers
Paul
