"this still doesn't explain the need to switch it to disabled in onafterrender... "
Because in my traffic light scenario, I want to return to the original state/value after the component has been rendered. If it were a traffic light, I guess once it turns red, it has to return to disabled. Is there an other type of event method that I could use to set a value, render the component and then return to the original value? -----Original Message----- From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] Sent: Tuesday, January 25, 2011 2:32 PM To: users@wicket.apache.org Subject: Re: Call onAfterRender and change default model without error this still doesnt explain the need to switch it to disabled in onafterrender... -igor On Tue, Jan 25, 2011 at 11:19 AM, Brown, Berlin [GCG-PFS] <berlin.br...@primerica.com> wrote: > Here is a use-case for my request below: > > Let's say I am implementing a traffic stop light Wicket component.
