NSView.alphaValue without Core Animation Layer?

Hi,

the documentation for -[NSView setAlphaValue:] states:

"Sending this message to a view that is not managing a Core Animation layer causes an exception."

But experiment under 10.6 shows that not only no exception is thrown, setting the alpha value on views without Core Animation layer even works just fine.

Is this a feature of Snow Leopard we can dependent upon? We were not able to find it documented, not even in the AppKit release notes for 10.6.

Thanks
Kai
