Hallo !

I would like to ask how I can catch an error produced by a Zpublisher
type cast. 

If I have an zpt with a html form with input box  <input type="text"
name="number:int"> then the Zpublisher tries to convert the string I
typed in into an integer number. If this fails, e.g. if I type in an
string "aaa" that cannot be converted instead of a number "123", then I
get this error:

Zope Error
Zope has encountered an error while publishing this resource.

Error Type: ValueError
Error Value: An integer was expected in the value 'aaa'


How can I catch this error ?


Thank you
