Hello, Im doing my best to get back into Tapestry a bit, but Ive got some questions.. How would I acheive something that renders a div based on whether a fields value is invalid. My use case:
a form for registering. You enter first name, last name, email, and password. The email has to be unique and i want to - as theyre typing or perhaps on blur - call the server and check the value entered against registered emails to determine if its alraedy in the system. If it is, id like to render a red message next to the text box and a green one if it's not in the system. I have a faint idea of the pieces I'd need for this, but frankly I could use some help thinking through my approach: -- in the java code generate some sort of link (EventLink? FormLink?) that knows how to create the event (where my dupe checking will be called ) and use addScript to pass it, along with the text fields id to the client -- on the client, i use ajax to hit that url and update the div i want and render the zone... or block? which is best? How do i make sure that the method that gets called 'sees' the updated domain object thats bound to the form? Do I submit the form? I don't want to invoke validation, though, just to check on the value of one particular text field and guide the user and she is entering. What's the "tapestry"-esque way of doing this?
