[Zope] - Best way to input validation

Oops, excuse me for the incomplete message. Here is the correct one: Hi, I've just notice that I had a misconception about how Zope handle input data validation. I thought it were possible to handle the errors, but it looks like we are doomed to show to the user the python traceback. I believe now that the way to go is to forget the :int and :required specifiers in form attributes and directly code the validation code. Am I right? If so, then besides prototyping there's no use to these specifiers. Is there a best way to validate input form data? regards, -- Paulo Eduardo Neves PUC-Rio de Janeiro Pager: Central: 292-4499 cod. 213 99 64 ou use a URL: http://www.learn.fplf.org.br/neves/mensagempager.html
