Using deferred promise in middle of chain..

[scottandrew]

How can you use a deferred promise int he middle of a chain? The only way I can see doing it right now is.

task { setup1() } then { setup2() } then { deffered() } then { promise -> val result = promise ?: throw(error) if result.isError() { throw(error) } else { it.get() } } fail { }

Unwrap doesn't seem to exist like is suggested.
