I found the problem. It's not caused by class array actually.
The following code demonstrate what I was trying to do:
var A = Class.create(...);
var B = Class.create(...);
Object.extend(B, {
A_ext: Class.create(A, {...}),
A_list: {
A1: Class.create(B.A_ext, {...}),
A2: Class.create(B.A_ext, {...})
}
});
The problem of above code is that when it try to reference B.A_ext, which
has not been initialized yet. And splitting the "Object.extend(B" to 2
extend actions solves the problem:
Object.extend(B, {A_ext: Class.create(A, {...}});
// now that B.A_ext has been initialized, we can use it safely
Object.extend(B, {
A_list: {
A1: Class.create(B.A_ext, {...}),
A2: Class.create(B.A_ext, {...})
}
});
