Test Code:

val test = mutableListOf<Promise<Int, Exception>>()
test.add(task { task { 1 }.get() })
all(test) success {
    // Never called
}

Note that Promise.of(1).get() works fine but not task { 1 }.get().

I can confirm that the inner task has been executed but somehow success is never called. I was trying to use this as fallback task, for example:

task {
    cache.get(key) ?: loadFromWebTask(key).get()
}

You could try task { task { 1 } }.unwrap().

Do you happen to have Kovenant configured with just one worker thread? Because in that case this indeed will block. It's not a good idea to use blocking methods like get in a mix with async methods. Like @friendoye suggested, you are probably want to use unwrap. Or just try to avoid nested Promises al together.

@mplatvoet I used the default number of thread. I have rewritten the code to avoid it though.
