<div>I would add that to get the callback to occur via AJAX add:</div>
<div>onChange: (html jQuery ajax serializeThisWithHidden)</div>
<div> </div>
<div>And in an attempt to make it clearer:</div>
<div>The parameter in the list: message is a collection of *objects* and the callback :value will be the selected object. If you give it a collection of string representations of your Stock objects, you will get back the selected string representation. But if you give it a collection of Stocks in this case, you will get back the selected Stock object. Seaside handles the bookwork for you in determining which object in the collection was selected. You don't need to deal with the selected index if you don't want to. <br>
