Making sure no user input is allowed whilst server is processing...[ajax for jsf]
Hello all,
I am wondering if it is possible to make sure that no user input is
possible/allowed whilst the server is processing in other words when the
"startText" of the a4j:status is displayed. Do I need some sort of a modal
component? Any best practice one of you could advise? How can I disable all
of the screen whilst the ajax request is processing??
Thanks in advance,
Julien.

Hi,
i take the following approach in order to get a freeze-screen during a
(native, non-ajax) request-response-cycle:
add the attribute onclick="waitDuringRequestDialogVar.show();" to your
command component which raises the submit.
<s:modalDialog dialogId="waitDuringRequestDialog"
dialogVar="waitDuringRequestDialogVar"
dialogAttr="bgColor='white' bgOpacity='0.5'
toggle='fade' toggleDuration='250'"
hiderIds="" styleClass="modalDialog">
<h:panelGrid styleClass="modalDialogProgressBox centerAlign">
<h:outputText value="#{text.modalDialogText_requestPending}"
styleClass="modalDialogText"/>
</h:panelGrid>
</s:modalDialog>
which in turn makes the whole screen freezing as long as the new page
is rendered.
I didn`t try it out on my own, but in case of an ajax-request i think
you need to call the "waitDuringRequestDialogVar.show();" just before
the xmlhttprequest-call.
cheers,
Gerald

A fancy way for doing modal windows and disabling other userinput are
either thickbox (http://jquery.com/demo/thickbox/) or greybox
(http://orangoo.com/labs/GreyBox/) - they both allow you to show
arbitrary content while users are waiting for background processing.
Just make sure you don't forget to add onUnload-Handler to your page,
to warn your users when they try the backbutton: Users on the web tend
to get impatient, use the backbutton and loose the whole page... (that
was at least our experience when we started using greybox)...

One thought...
You can use divs with z-index layering to accomplish this task. This will
allow you to use a transparent div on top of page (essentially functioning
as the glass pane in a Swing application).
