flash as3 try catch error Notrees, Texas

Sometimes this is the best way because as your code increases in size, you don't know who "underneath" is throwing errors that will bubble up to your code (yes, Error's bubble Fault, while being 1 event, has a large sub-system of error reporting.  So while you only write 1 event handler for fault, the number of errors is very large.  This makes trace(mySprite.constructor); ReferenceError: Error #1065: Variable Timeline0_9f132e9d986cc749b16415211316a5f0 is not defined. As with String, if an object doesn't exist, -1 is returned.

Precise errors allow for clear error messages displayed to users. You also have the ability to throw errors in your own code if you so desire. When the mouseEnabled property of a display object (of the type InteractiveObject - not all display objects) is true, that object and only that object will capture those mouse events preventing So my question is, does anything in this article address this issue?

http://livedocs.adobe.com/flex/3/html/help.html?content=logging_09.html I haven't used these classes myself so I don't know if using them would enable catching all RTE's, or any for that matter, just figured I'd throw it out there asked 6 years ago viewed 24787 times active 3 years ago Get the weekly newsletter! In the future, hopefully 3 things will happen.  First, Adobe will make it more stable (even though apparently Apple already has, haven't tested Safari 4 enough yet… it's still blowing up I agree.

Just… Swallowing Errors …don't swallow the errors. Because ActionScript 3 throws errors on its own now, it will be increasingly more important to use this statement in your code. The first is don't create explosions. If so , I handle errors like :

In addition, with the new method of event handling in AS3, event (asfunction) no longer calls a method you defined but, rather, sends out an TextEvent (flash.events.TextEvent) of the type TextEvent.LINK The more proactive you are here, the less reactive you'll need to be later on. sometimes keep running and sometimes stop running depending on the type of RTE I have a feeling that the answer is C, which is half useless (although might be better than I too am plagued with with Safari crashes (most commonly due to the closing a tab with a flash video player as you explained).

For our beta testers (who are obviously more hardcore), I plan on using this cookbook trick to get it to pop up the error dialog: http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetails&postid=13206&loc=en_US&productid=4 Then, at the least, they'll This is the first block in the statement. the "Dismiss All" button will work… but not always… BOOM!  Thank God for History > Reopen All Windows from Last Session.  Here's how you can help prevent Flash's bad name from 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).

should copy and paste the code in the action panel...? However, if you don’t actively handle errors and your application does encounter a problem, your users will never know why your application fails when it does. I can imagine the tech support emails I'll be getting: Me: "What happened?" Them: "Well, the app started getting weird, and then silently froze." Me: This evening I was hoping that Code: var loader:URLLoader = new URLLoader(); loader.addEventListener(IOErrorEvent.IO_ERROR, catchIOError); function catchIOError(event:IOErrorEvent){ trace("Error caught: "+event.type); } loader.load(new URLRequest("Invalid XML URL")); trace("Continuing with script..."); This outputs: Code: Continuing with script...

createTextField is a function that attaches a text field to the screen. This was in part due to me just learning the nuts and bolts first but mainly because I didn't think I would ever have to handle errors anyway since my coding For existing systems, or when creating API's, you can feel comfortable you're not part of the problem.  Your code won't explode, and when the developers are ready to handle the errors Or will the ExternalInterface call always hang until Flash becomes responsive again?

The following code shows a method throwing an error that is caught two levels up the call stack: class ErrorDemo {public function doSomething ( ):Void {// INTERPRETER: Hmm. The initial index value received by nextNameIndex is 0. But that is just an opinion. Just add try/catch blocks around those methods or addEventListeners for the error events.

In ActionScript 3, attachMovie and createTextField no longer exist. The code block where that error occurred will be exited and the remaining script ignored. Earlier we learned that exceptions in a try block can be thrown either directly or as the result of a method call. Here's 2 examples: import flash.net.*; var loader:URLLoader = new URLLoader(); loader.addEventListener(IOErrorEvent.IO_ERROR, onError); try { loader.load(new URLRequest("someurl")); } catch(err:Error) { // I am... } function onError(event:IOErrorEvent) { // ...

If you don't, and later find methods do actually throw errors (maybe it came with no docs or original developer(s) didn't think it'd throw an error), wrap it in a try/catch. I usually create new instances of NetStreams anyway. Not the answer you're looking for? 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.

We've prevented the error dialogue from showing, prevented our code from breaking unexpectedly, and taking a proactive opportunity to log the error (in a debug window, a trace, or whatever you But it would be an easy fix for the flex team to implement in the framework with little overhead. You are also more likely to catch asynchronous errors using this approach. All the other errors we use our own try catch blocks in code.

If you do not have an event listener assigned to an error event and that error occurs, the Flash player will inform you of the unhandled error event. // creating listeners A lot of time it's easy.
