Hi Folks, I have been building a slack clone with compose multiplatform with gRPC, I am facing an issue with compose UI crashing only on iOS with the following error :

Copy code

Uncaught Kotlin exception: kotlin.IllegalStateException: LayoutCoordinate operations are only valid when isAttached is true

I am on latest version of compose jetbrains, Has anyone faced this before ?

I haven't seen it, sounds interesting what the message says. I would recommend opening an issue in the GitHub repo if you don't get a response here

Hey there , I just had the same issue with this simple code : without the if part (which is the placeholder) it works just fine. But with the placeholder part, it crashes with the exception above when I clear str to empty string then type again. (Compose MP 1.4.0, Kotlin 1.8.20)

Copy code

val str = remember { mutableStateOf("") }
BasicTextField(
    value = str.value,
    onValueChange = { str.value = it },
    decorationBox = { innerTextField ->
        Row {
            if (str.value.isEmpty()) {
                Text("Aa")
            } else {
                innerTextField()
            }
        }
    }
)
