FMS & AS3

I find snippets of examples, like this one. Where is the official Adobe documentation of fms2 updated for as3?

This was in the livedocs section:

If you inexplicably get connection refusals to FMS using AS3, try adding the following line before you create your instance of NetConnection. I imagine a new version of FMS is on the way, but FMS <=2 can't understand your AS3 stuff, so this sets it to AS2 mode.

NetConnection.defaultObjectEncoding = flash.net.ObjectEncoding.AMF0;

Thank you, Zubaz!

He's absolutely right -- if you find yourself getting NetConnection.Connect.Failed errors trying to connect to Flash Media Server 2 using Actionscript 3, you need to add the line he mentioned above. I just wanted to confirm that the fix works.
