[flexcoders] Crazy mx.charts.Legend Runtime Error

[brianwebb01]

I'm getting a runtime error every time that I try to use addChild() to
add a Chart Legend to the application.  Has anyone ever seen this or
have any ideas?

Here is the error:

TypeError: Error #1007: Instantiation attempted on a non-constructor.

        at mx.managers::SystemManager/::docFrameHandler()


and here is the code that will do it:

addChild(new mx.charts.Legend());

that is a simplified line of code but it produces the same issue. 
I've looked at all kinds of examples and seen others to it without
issue but for some reason if I add a Legend I get the error.

Thanks.
