estanglerbm opened a new issue #953: URL: https://github.com/apache/royale-asjs/issues/953
flashplayer_32_sa_debug.exe throws this error: `VerifyError: Error #1053: Illegal override of A in a.A.` With this: ``` public interface B { function foo(c:Object):void; } public class A implements B { public function foo(c:String):void {} } ``` Royale mxmlc happily compiles this. Flex mxmlc will give this compile error: `Error: Interface method foo in namespace a:B is implemented with an incompatible signature in class a:A.` Why is this important? If you have: ``` import org.apache.royale.events.Event; class ... implements IEventDispatcher { ... public function dispatchEvent( event : Event ) : Boolean { ... } } ``` Royale mxmlc compiles it just fine. And it runs fine in JS. But in Flash Debugger, it throws VerifyError: Error #1053. The correct definition is: ``` COMPILE::SWF { import flash.events.Event; } class ... implements IEventDispatcher { ... COMPILE::SWF public function dispatchEvent( event : flash.events.Event ) : Boolean { ... } COMPILE::JS public function dispatchEvent( event : Object ) : Boolean { ... } } ``` And this kind of problem is hard to track down. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
