In Flash Player 10.1 and above, adobe has added the global error handler UncaughtErrorEvents. If errors generated anywhere in the world are not captured, they can be captured in the capture stage and the bubble stage.
The UncaughtErrorEvents object that schedules events is associated with a LoaderInfo object or a Loader object. Use the following properties to access the uncaughtErrorEvents instance:
: Detect uncaught errors in code defined in the same SWF.
: Detect uncaught errors in code defined in SWF loading of the Loader object.
If the content is running in the debugger version at runtime, an uncaught error dialog box appears when an uncaught error occurs. For these runtime versions, this error dialog box appears even if the listener is registered for the uncaughtError event. In this case, to prevent the dialog from appearing, call the preventDefault() method of the UncaughtErrorEvent object.
But the flaw of this method is that you don't know where these errors come from, that is, you cannot track the source of the message from the event, so you cannot do special processing on specific messages.
If your project is possible with version 10.1, so you'd better
Flex code :
if(("uncaughtErrorEvents"))
{
IEventDispatcher(loaderInfo["uncaughtErrorEvents"]).addEventListener("uncaughtError", uncaughtErrorHandler);
}
