flex default error handler Oquossoc, Maine

Assuming I could import the UncaughtErrorEvent, I would then do something like this to setup the event handler: if(systemManager.loaderInfo.hasOwnProperty("uncaughtErrorEvents")) { IEventDispatcher( systemManager.loaderInfo["uncaughtErrorEvents"]).addEventListener( "uncaughtError", uncaughtErrorHandler); } this all seems horribly kludgy but Why is water evaporated from the ocean not salty? Back to topExtending Bison for better error messagesThe first Bison feature of interest, hidden deep in the Bison manuals, is that it is possible to generate more meaningful error messages in Understanding Errors Error Types Before we look at how to handle the errors, lets first take a look at the errors themselves.

In developing ActionScript 3.0 applications, when you run your compiled code in the debugger version of a Flash runtime, a dialog box displays exceptions of type Error, or of a subclass, Working through an example In most cases, tests are verifying that appropriate use cases of a bit of code do what they're supposed to do.

My interpretation: The Flash player, at runtime, looks at what player your swf was targetted to, and "hides" the features that weren't in that version yet. –Wouter Coekaerts Oct 20 '10 This is a normal Flex SWF file that will be shown on a web page.

To make the example more interesting, the actual math in the body of a rule is implemented in a separate function. This method will be called when a requested page does not exist.

Flex, unlike Java but like most other languages, does not have checked exceptions/errors. If you handle them in the lexer all you can do is print an error and ignore them. All asynchronous errors are in the form of events, and they use the same event model as standard events. Finally I tried systemManager.loaderInfo.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR,globalUnCaughtErrorHandler.hanleUnCaughtError); And guess what, it works like magic.

To stop the dialog box from appearing, add: event.preventDefault(); so: private function onUncaughtError(event:UncaughtErrorEvent):void { event.preventDefault(); // do something with this error } I was using this in AIR, but I assume Better ReduceDiv() error messages |....+....:....+....:....+....:....+....:....+....:....+ 1 |a = 3; 2 |3 aa = a * 4; ...... !..^^...........

Going to be away for 4 months, should we turn off the refrigerator or leave it on with water inside?

This function is called when the generated parser detects a syntax error, invoking in turn the trivial function PrintError(), which prints enhanced error messages. Update 2010-01-12: Global error handling is now supported in Flash 10.1 and AIR 2.0 (both in beta), and is achieved by subscribing the UNCAUGHT_ERROR event of LoaderInfo.uncaughtErrorEvents. To use the location, you have to expand the rule-processing function as shown in Listing 12. Detail: This provides additional information about the error along with suggested solutions, if there are any.

You create an Error object by using the Error constructor function. You don't need to check for errors until you're ready to generate code. Listing 3 shows a sample grammar: Listing 3. It just doesn't work regardless of which loaderInfo I addEventListener on. –Rich Sadowsky May 17 '11 at 11:22 add a comment| 2 Answers 2 active oldest votes up vote 2 down
