My app was working fine until today. The probleme is that each request to amfphp return an error message like :
Client.Error.Message Send
Fail to send
In fact, this message is the fault function I put in the caller.
<s:CallResponder id="tracefilm"/>
<trace:Trace id="traceFilm" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" result="traceMaked(event)" showBusyCursor="true"/>
Because I don't know how to find where the problem is... I'll try to view what happens thanks to firebug plugin of FF during execution time.
The solution is simple. I've just fixed this issue in a old streaming app (100% flash).
If you encountered the problem in a old app, you propably don't have the crossdomain.xml file in the root directory of the web server. See Adobe explanation for more details.
I found the solution thanks to firebug. In fact, during Flash loading, the browser tried to access to a file called crossdomain.xml. Of course, the server response was 404 for my part...
You just have to create crossdomain.xml in the server, and to add this piece of code inside :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
Now your application, like mine will works again.
