Marcus Thiesen updated WICKET-5464:
-----------------------------------

    Attachment: ajaxwizard-quickstart.tar.bz2

This Quickstart demonstrates the issue and has an alternate implementation that 
does show how it can be avoided.

Does "master" mean it will be in 6.13 ?

> AbstractAjaxTimerBehavior does not work in combination with Wizards

> AbstractAjaxTimerBehavior calls stop() in it's onRemove() method. When used 
> in a Wizard onRemove is triggered by onActiveStepChanged. This disabled, but 
> never re-enables the behavior if the component tree is reused during wizard 
> stepping. 
> In my opinion it is more correct to disable the frontend timer but keep the 
> internal state of the Bahavior as is (or resetting headRendered to false as 
> the Behavior is in the pre render state after the onRemove) in order to 
> re-enable the Timer when the step using the Behavior is rendered again.
