Hi! One of test from demos named "Validating a form with a radio and checkbox buttons" behave strange from my point of view.
Checkboxes group Spam Spam via E-Mail Spam via Phone Spam via Mail show error message "Please select at least two types of spam.", if none or only one of checkboxes was checked before submit. This is correct. But this message disappear then I uncheck something. Looks like a bug. Serge
