Hey! I just walked through some sling example apps and I was missing an example to validate posted form data in sling. Sometimes you have to check if required fields have been set or an correct email has been provided. If validation fails the form should be displayed with the posted data again to the user with an error message and the data should not be stored. Validating the data with JS on client side seems not to be very secure because a user may disable the JS checks. How do you realize this kind of validation in "sling-style"? Writing an own POST-script or is there an another way?
cheers
