Hello everybody. I want to create some `Composable...

Hello everybody. I want to create some Composable function inside of an interface and realize this function in realizations if that interface. I have tried to use some @Composable callback getters (val renderer: @Composable () -> Unit), common functions (@Composable fun render()) and several other ways, but I got errors in rendering fun (IllegalStateException {message: 'Function TextArea should have been replaced by compiler.', cause: undefined, name: 'IllegalStateException', stack: 'IllegalStateException: Function TextArea should ha…://127.0.0.1:8080/postssystem.client.js:1:2202661'} error, TextArea here is external @Composable top-level function) or event getting an error java.lang.AssertionError: No such value argument slot in IrCallImpl: 0 (total=0). . Could somebody help me with this?

Can you provide a simplified reproducer?
What do you mean with: TextArea is external? This: @Composable external fun TextArea()? This won't work

[Ovsyannikov Alexey]

interface Renderer {
    fun render()

    class Default {
        @Composable
        override fun render()
    }
}

That construction do not lead to any error in compile time but lead to errors in runtime in case of calling @Composable fun, but if I will mark render as @Composable in interface, it will throw java.lang.AssertionError: No such value argument slot in IrCallImpl: 0 (total=0). in compile time

TextArea is the function in web compose

Which versions do you use?
This works for me (jsBrowserProductionRun), Kotlin 1.6.10 and Compose 1.1.1:

import androidx.compose.runtime.*
import org.jetbrains.compose.web.*
import org.jetbrains.compose.web.dom.*

fun main() {
    renderComposableInBody {
        A.Default.render()
        A.B().render()
    }
}

interface A {
    @Composable
    fun render()

    companion object Default: A {
        @Composable
        override fun render() {
            Text("Default")
        }
    }

    class B: A {
        @Composable
        override fun render() {
            Text("B")
        }
    }
}

Same with TextArea

Could you please try to replace realization in another gradle module and add here?

[Ovsyannikov Alexey]

I am using 1.6.10, compose 1.1.1, JS IR

Ah, you mean moving the interface into another module?

[hfhbd]

Works too 😄

Thanks, will try

[Ovsyannikov Alexey]

Could we make a call about this issue? I have tried your code and it works correctly, but in my case I am facing with errors

[hfhbd]

Do it 😄 But please include your code

[shikasd]

Make sure you apply Compose plugin to all gradle modules, it is likely the issue :)

[Ovsyannikov Alexey]

@shikasd your advise has helped

[Ovsyannikov Alexey]

@shikasd thank you :)
