…except in Flash Player 9. For some reason, the namespace mechanism doesn’t work for ActionScript 3 classes. This isn’t a big deal for playing existing content. All of my existing Flashcom apps I wrote in Flash MX 2004 & Flex 1.5 (Flash Player 7) still run just fine in Flash Player 9 in both Firefox & IE.
It’s when you have a server-side script do a NetConnection.call on an Flash Player 9 created SWF that things don’t work. You CAN call a method that your class has defined as public assuming you point the NetConnection’s client property to your class; protected and private don’t work. However, the namespace mechanism commonly used in ActionScript 2 doesn’t work with the server; it constantly reports method not found. You’d typically decorate the client side NetConnection object reference that you’re component got passed in via it’s loose interface “connect” method. This decoration with the namespaces pointing to your component allowed the server-side to find it. The server-side Flashcom Component Framework already has a built-in namespace mechanism that still works just fine.
You can emulate this by extending NetConnection, and making the class dynamic. Still, you’ll get the method not found error.
My only guess at the problem is I think it has to do with the lack of support of “slash syntax”. I’m not sure the new ActionScript Virtual Machine supports it. I know AVM does; it’s how Flash Player 4 SWF’s will work the same as they always have. However, it seems the FCS Component Framework utilizes this behind the scenes somehow. When you do this on the server-side:
nc.call ( this.callPrefix + "method" );
You’re basically going:
nc.call ( "YourComponent/InstanceName/method" );
…I guess. I gave up after 3 nights of trying to get it to work. I didn’t mind porting client code, but I didn’t want to port server-side code. Anyway, fix for me is to pass in the callPrefix as the first parameter to the method, and have the client side Observer class just parse out “who this message goes to”.
If you get it to work on your end, drop a note in the comments. I’m using Flex 2 & FCS 1.5 on Windows via Flash Player 9 in Firefox 1.5.
