Overriding on the Object Class

Hello wizards!

I’m trying to override some public functions of the Object Class, reaching no success. The Class I’m workin on extends flash.utils.Proxy. Below is the basic error description:

1020: Method marked override must override another method.

And if we remove the ‘override’ from the class signature, we got the following Error message:

1000: Ambiguous reference to isPrototypeOf.

I just can’t understand what is going on at all. Anyone here could point clues to bypass that behavior?

:thumb2: Tanks very much!
