Hello,
I already commented this but the message appears to have
disappeared - another try.
Explanation:
In the Application AS file, the prototype of a standard class A is
manipulated so that the class has event E. The event is dispatched
with "this.dispatchEvent({target:this,type:"E",...});
Now if I specify an event handler in an MXML file like <mx:A id="id"
E="doSomething()"/>, everything works just fine.
But: I also want to use class B which extends class C extending
class A, ie. B is a subclass of A. If I write like before <mx:B
id="id" E="doSomethingElse()"/>, the compiler says that the E
attribute is unknown.
So, this E event has to be declared all over again for class B??
What exactly does this mean?
