Probably show the same form and the completed data with an error message
indicating why some fields were not valid. At least a message in
portuguese, since most of my readers won't understand the english error
message. 

I was thinking about coding a javascript library to validate the data in
the client, but I'm convinced now that it isn't the way to go. If I use
the "automatic" error handling feature I *can't* properly (from a
usability view) handle it. 

Thanks for your answer Jim.
