next problem 🙈, I'm deriving another thing from `dealerAction`:

private val dealerButtonTrigger: PublishSubject<Unit> = PublishSubject.create()

init {
    dealerButtonTrigger.withLatestFrom(dealerAction.toObservable())
        .subscribe { (_, action) ->
            action.handle()
        }
}

Here, when I click (i.e. call

dealerButtonTrigger.onNext(Unit)

) after updating the dealer and navigating back, it still gives me the first dealer. Shouldn't it get the updated value?

This is exactly why I was asking this question in the previous thread: https://kotlinlang.slack.com/archives/C0B8Y8BHC/p1582647883026000?thread_ts=1582644781.011600&cid=C0B8Y8BHC

dealerAction

is a

Single

– it only emits a single value. It doesn’t have the concept of “updated value”. If the value can change over time, it should be an

Observable

, and the object backing

dealerAction

should have some way of signaling that the value changed.

right! I get it now. That's also why it doesn't work out of the box (without

toObservable()

)
