As3 Uncaught Error


If you've ever surfed the web using the debug Flash Player, Safari 3 and 4 explode all the time. If the regular Flash Player is being used, there is usually no sign of an error condition, but often things don't work as they should either (because the underlying error is Most do not bubble, so just by adding an event listener for it, you are preventing the error dialogue from showing.

Most of us are faced with them while coding software or while fixing bugs that have been reported e.g. But that is just an opinion. It is also worth mentioning here another advantage of the Flash Player Debugger version when working with errors in Flex development. The last parameter can be used to track the path to the project in which the error occurred. http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/UncaughtErrorEvent.html

As3 Uncaught Error

package { import flash.display.Sprite; import flash.events.ErrorEvent; import flash.events.MouseEvent; import flash.events.UncaughtErrorEvent; public class UncaughtErrorEventExample extends Sprite { public function UncaughtErrorEventExample() { loaderInfo.uncaughtErrorEvents.addEventListener( UncaughtErrorEvent.UNCAUGHT_ERROR, handleUncaughtError ); } private function handleUncaughtError( event : UncaughtErrorEvent A Loader object's UncaughtErrorEvents object is treated as a pair with the loaded SWF's LoaderInfo.uncaughtErrorEvents object for event propagation purposes. What our compiler doesn't find, the Flash Player will point out to us at runtime. So if you are interested, check back soon as I plan to publish the framework this month.

The stopImmediatePropagation() method still prevents events from being dispatched to all additional listeners. don't know if it's possible to work with the error class. This example is associated with the blog "Dustin's Software Cogitations and Speculations."

The ONLY error you can reasonably recover from is the 2nd SecurityError where you're hitting a port that's reserved or not open. As3 Catch All Errors Again, it makes sense that one would want this in development but would not necessarily want the average end-user with a regular Flash Player to see it.To illustrate the uncaught error Search or use up and down arrow keys to select an item.

Flex/Flash/Actionscript How are you doing global exception handling in Flex/Flash/AS3? Errorevent Like, application-is-totally-hosed type of seriously wrong. In addition, JavaScript errors in HTML content loaded in an HTMLLoader object (including a Flex HTML control) do not result in an uncaughtError event. swallowing it.  When creating your own errors, make sure you dispatch an event that extends Event instead of ErrorEvent so you don't force explosions on those (including yourself) using that code.

As3 Catch All Errors

Anyone Understand how the chain rule was applied here? http://www.ericfeminella.com/blog/2009/11/08/global-error-handling-in-flash-player-101/ Flash Player 9 and 10 have errors.  These are like Java's unchecked exceptions.  There are 2 types of errors: synchronous and asynchronous meaning "immediately happening while your code is running" and As3 Uncaught Error Now we have a great complier, and a great runtime that will actually show a dialogue of these errors with where they actually occurred, and why.  The problem is, unhandled errors Loaderinfo As3 In those cases a return code that signals that error is appropriate.

The javascript approach is interesting but I would assume it would be rather flaky. Parameters type:String (default = NaN) — The type of the event. bubbles:Boolean (default = true) — Determines whether the Event object participates in the bubbling stage of As3 Throw Error

Often, however, it's the bloody Factories; classes or just functions responsible for parsing the data. ReturnsString — A string that contains all the properties of the UncaughtErrorEvent object.

When this is written, flash builder 4 doesn't have a native way that lets you use it, so we have to do a little mix. (Update: The update is out.) The As3 Try Catch Thus you must listen to the loaderInfo's uncaughtErrorEvents property of your topmost display object: loaderInfo.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR, uncaughtErrorHandler); share|improve this answer answered Aug 23 '10 at 10:26 grapefrukt 18.5k43866 Still no The first is opinion (which I agree with) and the second is fact.

It's duplicated within the Adobe bug database a few times, and even one of the duplicates is the second most voted on bug in the AS Compiler bug database (https://bugs.adobe.com/jira/browse/ASC-3139).

You should view catch blocks as your opportunity to provide the user with a meaningful dialogue on what happened, and/or what they can do to continue. The second drawback relates multi-version software, where Airbrake is lacking of a reset button for errors. While Java's throws keyword does help you via the compiler recognizing it and ensuring your code handles it… why are they doing this? Additionally, you leave surprises for the other developer (maybe even you) when using the code since there is no way for them to know it'll do that unless they are intimate

Browse other questions tagged actionscript-3 flash error-handling global or ask your own question. One of the main illustrated points in this example is that the Error.getStackTrace() method returns null when the regular Flash Player is used and only returns a not-null value when run The pro, however, is that you know what you're dealing with, and the compiler helps you. Coding Photography About Tracking of client errors in ActionScript 30/04/2013 by Stephan Partzsch | 2 Comments Probably everybody is familiar with errors in Adobe Flash.

If your MovieClip is null, then instantiate it. …however, why not just check for null first? I've reduced it to a very simple program much like above except with all the code in the main mxml file.

I have not tried it out yet, but as long as it comes with the option for per version tracking, it would be really helpful.

So, the errors you know and don't know are fine; that's the point of this article. A lot of times you may feel like you'll reach the inevitable conclusion, "they're screwed". The framework will provide a foundation from which more robust exceptions can be defined (in comparison to the generic Error class), as well as common exception types which implement the framework.
