First of all, if you have not gotten ready for Flash Player 10.1 by integrating the playerglobal.swc into either Flash CS4 or CS5 you can read up on how to do that here.

Now, after many questions, I thought I would dive into why using Test Movie (cmd(cntrl)+enter) from Flash CS4 always gives “ReferenceError: Error #1065″ when trying to use a 10.1 specific function. This happens even after updating the Stand Alone players.

I’ve narrowed this down using Capabilities.version and Capabilities.playerType like so:

********************
import flash.system.Capabilities;

trace(Capabilities.version);
trace(Capabilities.playerType);
********************

It appears that the IDE uses an integrated player for Test Movie, and not the Stand Alone player, as you would think it would. Instead, Test Movie produces a player type of “External.” Whatever that means. Which is the player run by the IDE itself.

So how do you work around this?

Well, you don’t. I have torn through every file I could find to see where Flash is targeting the player – or the “External” player itself, and I just can not find it. I can’t even find it in the app package (right clicking and going to Show Package Contents on the Mac). Needless-to-say this is frustrating.

But, there is some hope. You can use Debug Movie (cmd(cntrl)+shift+enter) from the IDE to use the Stand Alone debug player which will give you full access to Flash Player 10.1. Here’s what the two ways to test should do in CS4:

This same issue happens in Flash CS5. Although, if you have run the update to 11.0.1, you should be able to use Flash Player 10.1 API without problems. This is what the two ways to test should give you:

Of course, you can always Publish and open your SWF/HTML in your browser, even though that is a pain.

Unfortunately, I don’t foresee a real fix for this coming anytime soon, but it sure would be nice. If I find anymore information or a way to fix it, I will be sure to let you know.

Happy Flashing!
