> I never reproduced it on local, it happens a lot on linux server behind
> apache proxy(could be just coincidence). I could try to debug it, if you have
> no idea why it could happen. It also seems that it happens only after server
> is running for some time.
> I am sending multiple events to update different panels from asynchronous
> process like this:
>
> EventBus.get(Application.get(WicketApplication.class.getName())).post(new
> ComponentBuildEvent());
> 15:16:36 ERROR o.a.w.DefaultExceptionMapper [refreshExecutor-4]: - Unexpected
> error occurred
> java.lang.IllegalArgumentException: Argument 'page' may not be null.
