[Zope] - Best way to input validation

[Paulo Eduardo Neves]

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,
