Hi Richard,
I suppose you're not using the PPR API to show the "Loading..." message. If
so the message should appear only after the client validation. I suggest you
start using the PPR start/stop events. From the developer's guide:
Monitoring AJAX requests
If you want to be notified when the client is busy waiting for an AJAX
response, add a "state change listener" to the request queue:
TrPage.getInstance().getRequestQueue().addStateChangeListener(myCallback);
Your callback will be passed a single parameter, which will be either
TrRequestQueue.STATE_READY or TrRequestQueue.STATE_BUSY, depending on the
current state of the request queue. The statusIndicator component uses
exactly this mechanism to know when to start and stop spinning its
indicator. You can optionally pass a second parameter to
addStateChangeListener() for the "this" you want active when your callback
is notified.
Sample code:
<script type="text/javascript">
// <![CDATA[
function myCallback(state){
if(state == TrRequestQueue.STATE_BUSY) {
//START OF PPR
} else if(state == TrRequestQueue.STATE_READY){
//END OF PPR
}
}
TrPage.getInstance
().getRequestQueue().addStateChangeListener(myCallback);
// ]]>
</script>
I hope it helps.
