form validation replace busybox in loginpanel

[norber...@multimageweb.com]

hi,

We want to replace login box busybox alert by simple form validation tooltips.

example https://www.zkoss.org/zkdemo/input/form_sample. something similar is implemented in forms - generate shipment (manual) - attached screenshot.

login panel is not form so looking for workaround how to...

thanks
