Well using the observe_form helper you can pass the current values of the form to an action to do verification server side and then return a result. Not ideal with the new forms system but I am sure there must be a way (I have not investigated as of yet) to use your existing validation setup in your forms class to pass back a result and so enable the submit button for a form etc.
Personally I feel that the forms framework should include an easier way to do client side validation as more and more web apps are moving away from the submit-entire-page process to accept form input. Before the Web 2.0 "revolution" (for want of a better word) the forms framework would have been fine but the asynchronous requests are now a part and parcel of developing a web app not an oddity or exception. Or at least thats my take. On Thu, Mar 26, 2009 at 8:52 AM, James <thenet...@gmail.com> wrote: > This is one of the things I dislike about the new forms system.
