uncaughtError event when a runtime error occurs and the
error isn't detected and handled in your code.
Use the following properties to access an UncaughtErrorEvents instance:
-
LoaderInfo.uncaughtErrorEvents: to detect uncaught errors in code defined in the same SWF. -
Loader.uncaughtErrorEvents: to detect uncaught errors in code defined in the SWF loaded by a Loader object.
To catch an error directly and prevent an uncaught error event, do the following:
- Use a
try..catchblock to isolate code that potentially throws a synchronous error - When performing an operation that dispatches an event when an error occurs, register a listener for that error event
If the content loaded by a Loader object is an AVM1 (ActionScript 2) SWF file,
uncaught errors in the AVM1 SWF file do not result in an uncaughtError
event. In addition, JavaScript errors in HTML content loaded in an HTMLLoader object
(including a Flex HTML control) do not result in an uncaughtError event.

public function UncaughtErrorEvents()| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Creates an UncaughtErrorEvents instance. Developer code shouldn't create UncaughtErrorEvents instances directly. To access an UncaughtErrorEvents object, use one of the following properties:
LoaderInfo.uncaughtErrorEvents: to detect uncaught errors in code defined in the same SWF.Loader.uncaughtErrorEvents: to detect uncaught errors in code defined in the SWF loaded by a Loader object.

flash.events.UncaughtErrorEvent.UNCAUGHT_ERROR| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Dispatched when an error occurs and developer code doesn't detect and handle the error.
Defines the value of thetype property of an uncaughtError event object.
Note: If in a try block, there is an event dispatcher that calls its event handler,
the catch block doesn't catch the error if thrown in event handler. Any error thrown
thereafter can be caught by listening to LoaderInfo.uncaughtErrorEvents.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | true |
cancelable | true; cancelling the event prevents the uncaught error dialog from appearing in debugger runtime versions |
currentTarget | The object that is actively processing the Event object with an event listener. |
error | The uncaught error. |
target | The LoaderInfo object associated with the SWF where the error happened. |
text | Text error message. |
