flex - Can I make Flash Builder break on TypeError or ReferenceError? -

right flash builder telling me have these errors when i'm debugging, won't tell me line numbers , can't figure out how make break when errors occur. possible?

example console output:

typeerror: error #1009: cannot access property or method of null object reference. referenceerror: error #1056: cannot create property is_flying on entities.bird. 

thanks!

ok, based on last comment have 2 suggestions:

try adding uncaught exception handler app. in event handler, can print own stack trace see error coming from.

private function uncaughterrorhandler(event:uncaughterrorevent):void {     // note suggested doing this, might details     // out of event object passed function     var e:error = new error('hi');     trace(e.getstacktrace(); } 

alternatively, since 1 of errors mentions is_flying property, find places property set , wrap code in try/catch block.

finally, weird scenario , coworkers experiencing. if can identify/reproduce problem, may want submit bug adobe.
