Is it not possible to read from a

@Model

var outside a

@Composable

?

It is possible. At the moment either you must read/write on the main thread or use some of the tools in

Frames.kt

to set things up to manipulate

@Model

objects on other threads but we plan to make this much easier

I wonder why this fails then. The last line in the trace corresponds to line 8 here

the FrameManager gets set up after you call setContent with your composable for the first time

Nice, thank you. That works
