Thanks, I will give it a try.<br><br>I thought of the optimization because the "onchange" attrubute of the select tag contains a lot of javascript code. If I don't update the code on each ajax request it could save time on both the server and client.<br>

Well, the callbacks are stored in the RenderContext, which is in the<br>
ActionPhaseContinuation. There's no provided API for getting the<br>
current action phase continuation at the moment, but it would be in<br>
the context stack and you could look it up again from the session<br>
based on the _k key. Maybe we should be stashing it in a<br>
RequestContext property so it is accessible - might be a useful thing<br>
to have around. As a test, you could customize<br>
WASession>>handleFiltered: to do that.<br>
<br>
I have no idea how beneficial the optimization would be, off the top of my head.<br>
