Handling bad connections

[yoghoyogho]

I'd like Richfaces to fail fast when the connection is lost or the server somehow can't be reached. How can I notify the user that the server is not being reached when for example I'm doing a a4j:form post ? I've tried shutting down the server and doing a post and I still get to see the a4j:status screen I've built in. The post will fail (I can see it failing in Firebug) and the oncomplete event of a4j:status is fired.
For the user this seems like his request has succeeded, but in fact it didn't.
I'd rather see a warning that the server can't be reached.
Can anyone be so kind to point me in the right direction how to solve this issue?

our components has ontimeout attribute. Event fired when the request timed out.

That's a blazing fast reply :-)

Let me be more specific:

<a4j:form id="orderForm" ajaxSubmit="true">
 <a4j:status id="orderStatus" onstart="showStatusModal();" onstop="hideStatusModal();"/>
 <a4j:jsFunction name="sendOrderValue" action="#{orderBean.orderArticle}" reRender="articlePanel">
 <a4j:actionparam name="count" assignTo="#{orderBean.count}"/>
 <a4j:actionparam name="item" assignTo="#{orderBean.item}"/>
 </a4j:jsFunction>
</a4j:form>

Where would ontimeout need to be inserted? I ask this, because I don't see ontimeout documented for both a4j:form as a4j:jsFunction

sorry for confusing you.. Thinked about timeout attribute.. Now will check and clarify..

I've used timeout on command button defined to 1000mls and in the button action used thread.sleep(3000); to simulate the timout.

for this case out standard error handlers described in documentation "basic concepts" section works fine:

<script type="text/javascript">
 A4J.AJAX.onError = function(req, status, message){
 window.alert(status + message);
 }
 </script>

500 Request timeout alert appears. You could redefined the handler code with any you need.

This was exactly what I was looking for. I've tried it and it works. Thanks a lot!
