Are you able to use an #onSuccess: type message is your system? (Ajax request.)

> Hi all. I've built a fairly complex interface using SmallFaces
> 9 listboxes, 4 buttons, 3 labels, 1 panel and two custom components
> (subclasses of SFAbstractWidget - search results and a map). Selecting
> an option in one listbox results in a chain of events being executed -
> the contents of two other listboxes are updated, a search conducted on a
> remote server and the results being displayed including label and button
> statuses being updated. There are no submit or search buttons -
> selecting a listbox option starts the process (I will be adding the
> functionality to include the search button should the user not have
> The challenge I have is due to the delay in getting data from the remote
> server I would like to implement a "please wait" message while the data
> is being retrieved. I am not having any success getting it to work.
> I tried a SUPeriodical object reading a variable holding updated message
> text but, it stops while the data is being retrieved and will display
> the content only when the remaining components are updated -- too late.
> Is it possible to have an element update the content and display the
> results before the remainder of the requests are processed? What would
> that look like? Does SUEvaluater/updater update content and render
> before processing the next script?
> I was looking at Ramon Leon's Ajax Polling and Concurrency articles
> thinking I may have to head in that direction. Is that the direction I
> need to head in? Any suggestions would be helpful.
> As you can tell I am confused about the sequence when a element on a
> page has it's content updated and when the browser displays the results
> using ajax.
> Thank you for the help.
