Custom validation message for 'int'?

I cannot seem to find a way to provide a custom validation message for 'int'. (I learned for most others). '-' is not a valid int. fieldName.int does not work fieldName.Integer does not work fieldName.Number does not work fieldName.NumberValidator.range works but it's a different message.

How not to show a popup - Or stop it in its tracks?

Thanks for the help guys. This link opens a popup all right yet when the condition fails, onClick() returns regardless and opens the parent page in the popup. I don't know how to deny the popup to come up at all. Thanks. Florin -- View this message in context:
