document.frameRate, how do I use it ?

[pcarini]

I'm looking to get what frameRate a flash movie is set to at runtime, in the simplest way possible. The document.frameRate property seems like it'd be easy enough to use, but if I trace I only get undefined.

The flash help shows this: (to set it, but I'd imagine I could read it also)
fl.getDocumentDOM().frameRate = 25.5;

My trace looks like this:

trace(_root.document.frameRate);
trace(_root.getDocumentDOM().frameRate );

Both return undefined. Any ideas ?

Thanks for any help,

this is for javascripting in the ide, so it won't work in a swf.
