flash - ActionScript Compiler UncaughtErrorEvent -


after using asc2 compile air application, found error stack trace missing while catching uncaughterrorevent.

here example code:

var root:sprite = this; root.loaderinfo.uncaughterrorevents.addeventlistener(uncaughterrorevent.uncaught_error,errorhandle); throw new error("test");  protected function errorhandle(event:uncaughterrorevent):void         {             var message:string;              if (event.error error) {                  message = error(event.error).message;                  message+="\n"+error(event.error).getstacktrace();             } else if (event.error errorevent) {                  message = errorevent(event.error).text;             } else {                  message = event.error.tostring();              }          }

while using asc1, can see full stack trace in error handle. using asc2, empty stack trace.

anyone have same problem?

how uncaughterrorevent stack trace?

don't cast event.error error, in:

error(event.error).getstacktrace()

getting error's stack trace returns call stack error @ time of error's construction string. note line number of stack trace line of cast.

instead, call getstacktrace() event.error, in:

event.error.getstacktrace()

there's nothing significant on stack per example.

adding recursion helps demonstrate issue:

package {     import flash.display.sprite;     import flash.events.uncaughterrorevent;      public class exceptiontest extends sprite     {         public function exceptiontest()         {             super();              loaderinfo.uncaughterrorevents.addeventlistener(uncaughterrorevent.uncaught_error, uncaughterrorhandler);             recursion();         }          protected function recursion(depth:uint=0):void         {             if (depth == 5)                 throw new error("test");             else                 recursion(++depth);         }          protected function uncaughterrorhandler(event:uncaughterrorevent):void         {             trace(event.error.getstacktrace());         }     } }

...would produce:

error: test     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:19]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:13] [swf] users:jsturges:dev:flash-workspace:x:bin-debug:exceptiontest.swf - 1,745 bytes after decompression error: test     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:19]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:13]

if uncaughterrorhandler() changed example casting error, in:

protected function uncaughterrorhandler(event:uncaughterrorevent):void {     trace(error(event.error).getstacktrace()); }

the debugger catches exception, getstacktrace line of cast:

error: test     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:19]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest/recursion()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:21]     @ exceptiontest()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:13] [swf] users:jsturges:dev:flash-workspace:x:bin-debug:exceptiontest.swf - 1,519 bytes after decompression error: error: test     @ exceptiontest/uncaughterrorhandler()[/users/jsturges/dev/flash-workspace/x/src/exceptiontest.as:26]

there may nuances marshaling as1 , as2 as3 supports uncaughterrorevent starting @ flash player 10.1.

beyond that, assure appropriate debug player per actionscript version. in non-debugger version of runtime error.getstacktrace() method returns null.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
