Hello Jonathan,
you've posted nice example so I've decided to investigate what you
described even if i'm not very experienced dev yet,
so first I wrote a simple jsp page that simply returns xml data (your
dummy.xml is a content returned) with added Thread.sleep(....) used to
sustain results for few seconds, Even if I changed response time to
minimal values there was no change in dashboard behavior, charts are
not updated with remote call, DataGrid data are correctly updated,
That was strange for me because I've already ported Flex Dashboard
sample to Cairngorm and it works fine when data is requested from server,
So I next moved HTTPService and onResults/onFault handlers to
Application that way:
<code>
.....
initialize="initApp()">
<mx:HTTPService showBusyCursor="true"
id="GetSalesData"
url="http://localhost:8084/dashboard/cfm/sales.jsp";
result="onResult(event)"
fault="onFault(event)"/>
<mx:Script>

....
that is moving business logic into main code and there is no change,
DataGrids data are updated but charts are not,
with that solution I'm not using Cairngorm for data requests at all
using basic HTTPService solution,
I think there is rather something in bindings and Charts with that
specific solution because as I mentioned I've already existing
Cairngorm based sample which updates bindings without problems,
Also Renaun mentioned bindings working fine with AMFPHP based
Cairngorm implemenation,
hth,
kind regards,
