Description

I have a ModalWindow which shows a panel with a hidden label with an AjaxSelfUpdatingTimerBehavior. When the modal window is shown, the following error occurs in the Wicket Ajax Debug console:

ERROR: Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript: TypeError: Cannot read property 'label5' of undefined, text: (function()

{clearTimeout(Wicket.TimerHandles['label5']); delete Wicket.TimerHandles['label5'];}

)();
