Thanks Ramon! It works great!!
One last question about conditions. How can i override the default
message for beRequired? When i add a custom condition i specify it
with the labelled: argument.
Or maybe better.. give localizated messages.. am i asking too much? xD
P.D.: onsmalltalk.com it's great! Awesome writing :D
