I am working on an existing project with a very big recycler view (chat feed) i have a component that is written in compose and is introduced by inflating an XML viewHolder with ComposeView in it.

When i try to measure this view i get

IllegalStateException: Cannot locate windowRecomposer; View androidx.compose.ui.platform.ComposeView{6542dd8 V.E...... ......I. 0,0-0,0 #7f0a0206 app:id/composeView} is not attached to a window

If i dont try to measure the view everything works fine.
It crashes even if i dont invoke setContent

What can be the problem?

Which version of compose? Is the xml inflated into a subclass of ComponentActivity?

Compose 1.2.0, inflated onto AppCompatActivity.

1.2 is quite old at this point, if you can repro with 1.4 then please file a bug.

Hello 👋

I’m having the same issue.

Do you have any solution or is it fixed with Compose 1.4?
I tried on Compose 1.3.2, but I still have the same crash 😞

N.B I’m not using Compose 1.4 right now because I can’t use Kotlin 1.8 (because of Kotlin Poet compatibility).

Feel free to file a bug so we can track this if it is actually still happening in newer versions

Hi,

So finally, the issue seemed to be between Flexbox and Composeview.

I’ve solved my issue by replacing my RecyclerView + FlexboxLayoutManager by a FlexboxLayout.
