Is it about ref ?

[Robert Jaros]

Yes

[Robert Jaros]

I found something about RefCallback and it does seem to work here: https://github.com/rjaros/kvision/blob/master/kvision-modules/kvision-react/src/test/kotlin/test/io/kvision/react/ReactSpec.kt#L41-L54
But I'm not sure this is correct and I get a warning from react in logs about wrong use of hooks.

If you want in place call - use RefCallback factory (not hook)

[Robert Jaros]

Tests are passing, the warning is gone. Thank you 🙂

Hook - for memoization

[turansky]

If memoization ist’s required - you can use factory method
