I can't really see your mistake from the code, but anyway, here are
two things that could be wrong:
1. for client-side validation to work, you need to set the
clienValidationEnabled parameter of your form to true
2. be sure to bind the form's delegate-parameter to your delegate.
3. if you want server-side validation check the delegate bean using hasErrors
