On "listbox", there is an error when "auxheaders" are using "datebox" components. It appears when "listbox" recibe an event from @NotifyChange, and show this log on console:

Uncaught TypeError: Cannot read property 'value' of undefined

Thanks for reporting this bug. I have found a reproducible example, please see https://tracker.zkoss.org/browse/ZK-4632

If you notify a change for a ListModelList, then the workaround is

Don't notify a ListModel.

Because when you call its methods e.g. add(), remove(), ListModelList will fire event to notify Listbox, so you don't have to specify it in @NotifyChange.
