Muchas gracias para tu ayuda! I have one last question. When the form
submits, I get all these validation errors, which makes sense, because
normally when I submit my form, I have to validate certain fields.
But in my case, when the value of that text box changes, I want to submit
the form (to re-populate another select menu) but I DON'T want to do
validation. Is there any way to skip the validation phase when the only
reason I want to reload the page is to re-populate the selectOneMenu?
Thanks, - Dave
