That depends. Did you buy the book? :-)

Where the Bundle is an out parameter?

That doesn't need an out parameter. That's an in parameter -- you are
passing the data *to* the callback. And, since in is the default
direction, you don't need the keyword at all.
Rolling back to my sample, I do the same thing you do, minus the out:
interface IScriptResult {
void success(String result);
void failure(String error);
}
>From your original post on this thread, you have:
interface IGameInterfaceResult {
void success(out Map result);
}
I misunderstood your situation, which is why the Map success()
approach won't work. But, you might try:
interface IGameInterfaceResult {
void success(Map result);
}
since you don't need the out, and the out is technically wrong in this
case as I understand it. It may be that "out Map" doesn't work,
generating the flawed code you found.
Even if you're using Bundle successfully, I'd drop the out. You'd use
out if the *callback* were trying to pass data in success() back to
the *service*.
