Victor,
I'm not sure if it's correct or incorrect as far as the definition,
but it would appear the "-" after the 9 isn't being treated as a
character, but a range.
The following seems to give your desired result.
"^[_A-Za-z0-9\\-]+(\\.[_A-Za-z0-9\\-]+)[EMAIL PROTECTED](\\.[A-Za-z0-9\\-]+)*$"
Perhaps someone more knowledgeable with regexp than myself could tell
you if it's the definition that's incorrect, or the implementation.
Cheers,
Aaron
