Yes, it is because you are using an auto managed widget. I advise
using a modal widget and skipping the auto_manage bits.

Ehm the fact is that I'm having problem with how to redisplay the
original widget..
Could you please explain what you mean?
I'm wondering if the problem is related to the fact that I used an
AUTO_MANAGE widget..

If nothing else you can always have your error message say "You need
to fix your values" or something to that effect, then just redisplay
the original widget, check it again, and repeat as necessary...
