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!
