Hey, I’ve recently started using mvikotlin with decompose in a project, and run into an issue when using any Bootstrapper, but SimpleBootstrapper

After configuration change this exception occurs on application launch:

java.lang.IllegalStateException: Value is already initialized: Function1<Action, kotlin.Unit>
        at com.arkivanov.mvikotlin.utils.internal.AtomicExtKt.initialize(AtomicExt.kt:7)
        at com.arkivanov.mvikotlin.extensions.coroutines.SuspendBootstrapper.init(SuspendBootstrapper.kt:26)
        at com.arkivanov.mvikotlin.main.store.DefaultStore.<init>(DefaultStore.kt:58)
        at com.arkivanov.mvikotlin.main.store.DefaultStoreFactory.create(DefaultStoreFactory.kt:21)

Although this is easily avoided by using SimpleBootstrapper, I’m wondering is this behaviour intended or is there something that we have to do to prevent the exception from happening?

The issue can be reproduced in decompose or mvikotlin sample app by replacing the SimpleBootstrapper by Suspend/ReaktiveBootstrapper

[Arkadii Ivanov]

Could you please show a code of the bootstrapper?

[steelahhh]

private object BootstrapperImpl: SuspendBootstrapper<Unit>() {
    override suspend fun bootstrap() {
      dispatch(Unit)
    }
  }

or whatever is the alternative with reaktive

[Arkadii Ivanov]

Yeah, the bootstrapper must not be object. We should mention this in the docs. Contribution is welcome 😀

[Arkadii Ivanov]

Btw, how do you add Decompose to your project?

[steelahhh]

I’m using includeBuild for now, since I was tweaking some of the internals

[steelahhh]

I also wasn’t able to import it as a normal library, but I see that the issue is already filed

[Arkadii Ivanov]

Yeah, I need to figure this out.

[Arkadii Ivanov]

Thanks for your input!
