Possible to use TLFTextField as target of FLVPlaybackCaptioning?

programming flash

Does anyone know if it’s possible to use a TLFTextField instead of a normal text field as the target for the output of the FLVPlaybackCaptioning component?

Everything works fine with a normal TexField, but when I point it at a TLFTextField created with AS, it fails and gives me this:

Coercion failed: cannot convert "pooh" to flash.display.DisplayObject.

when I run:

my_FLVPlybkcap.captionTarget = "pooh";

Thanks!
