It looks like there's a few things you may or may not be doing with your code that I see. I don't necessarily have a solution for you, but maybe this will get you on the right track:<div><div><br></div><div>First of all, for your sanity, you may want to separate out your callback functions as separate methods. It makes the code a lot easier to follow.</div><div><br></div><div>Also, callbacks are simply functions that can be passed around just like a variable. They're known as anonymous functions also, if that helps. They are not overused in Seaside at all. In fact, many languages use them as a core aspect of their architecture (ie. NodeJS). Callbacks should be your best friend :) They are intrinsic to any asynchronous pattern (ie. Ajax). Here's a simple example:</div><div><br></div><div>I ask the server for something (ajax GET request).</div><div><div>Now, I don't know when the server is going to get back to me with the answer, or if at all, but what I can provide is instructions for what to do with a successful or failed response.</div><div>That's what the callback is doing for me.</div><div><br></div><div>I don't know much about Scriptaculous, but I think you probably want the ajax request object instead of updater. There should be a way to configure updater so that you serialize the form and send that data serverside.</div><div><br></div><div>Also, #<span style="font-size: 10pt; ">renderTheListWith:on: doesn't need to do any rendering stuff. Your callback in the updater can deal with that.</span></div><div><br></div><div>RS </div><div><br><div><div id="SkyDrivePlaceholder"></div>> To: seaside@lists.squeakfoundation.org<br>> From: intrader@aol.com<br>> Date: Mon, 27 Aug 2012 22:06:24 +0000<br>> Subject: [Seaside] Re: Help with JQuery example<br>> <br>> intrader <intrader <at> aol.com> writes:<br>> <br>> > <br>> Thanks both for your answers.
