It doesn't work; it has bugs and doesn't make clean, deep copies. ----- Original Message ----- From: "Mark Walters" <[EMAIL PROTECTED]> To: "Flashcoders mailing list" <flashcoders@chattyfig.figleaf.com> Sent: Monday, January 09, 2006 12:27 PM Subject: Re: [Flashcoders] Duplicating an object without pointing to originalone
If you download the FlashRemoting source code, ( http://download.macromedia.com/pub/flashremoting/mx2004/components/actionscript_2.0/flashremoting_comp_sourcecode.zip ), you will have a new class mx.utils.ObjectCopy ... this will make a new object, instead of a reference to the first.
