Re: [Flashcoders] Inheritance bug in AS2 Flash 8

2006-09-28 Thread Hans Wichman 

Hi,
not 3 times? I don't think its being called twice in class2, class5's
superclass is class 4, which doesnt not redefine class2's method.
Let class 5 extend class2 for testing purposes, it probably will work
correctly and introduce class3 to see what it does. Then override method1 in
class 3 to see what it does.

Hi list, I'm creating a framework in my job and I have reached this

Class1 defines a method, for example method1.
Class2 overrides the method and calls super.method1.
Class5 overrides the method and calls super.method1.

When a instance of Class5 is created, and calls method1, method1 is
called twice in Class2, wtf?

You can reproduce the bug using this sample classes:
code
class Class1 {
   public function method1():Void {
   trace(class1 method1);
   }
}

class Class2 extends Class1 {
   public function method1():Void {
   trace(class2 method1);

class Class4 extends Class3 {
}

class Class5 extends Class4 {
   public function method1():Void {
   trace(class5 method1);
   super.method1();
   }
}
/code

And this in the main timeline:
code
var a:Class5 = new Class5();
a.method1();
/code

The output is something like this:
class5 method1
class2 method1
class2 method1
class1 method1

Re: [Flashcoders] Inheritance bug in AS2 Flash 8

Save the example classes in a folder and look at the output console in 
Flash. You will see:


class5 method1
class2 method1
class2 method1
class1 method1

This doesn't have any sense.

If you override the method in class4, or in class3, like this, it works 
fine:


code
Class4 extends Class3 {
   public function method1():Void {
   super.method1();
   }
}
/code
The output in this case is:
class5 method1
class2 method1
class1 method1

But I don't wanna override the method in Class3 nor Class4 to do nothing 
but call super, because is not needed in a OOP language.

Hi,
it's discussed here as well, ut i do not know of a fix other than that
described in the post below.
If you dig into the nitty gritty prototype chain information available on
flash you might be able to fix it.

Re: [Flashcoders] Inheritance bug in AS2 Flash 8

Sounds like the inheritance chain

Theoretically, seems like when Class 3  4 don't implement the method, the
line of execution goes up the chain until it is: Class 2.
