@ron If you remember, all of the builder functions are extending EventTarget, because there is no common super type for all JavaFX "constructs". Not even Node is a common super type. However, since almost everything in JavaFX extends EventTarget it's possible to call some extension functions on parents where it just doesn't make sense. Are you saying that you get this error if you call runAsyncWithProgress on an HBox? I wouldn't think that would fail, and it should work for sure.
