What does this: Caused by: java.lang.IllegalStateException: Composition requires an active composition context mean? What are the possible causes?

[kioba]

based on the some quick search seems like the composition context is for to contain the Slot Table and it it referenced as a root. My assumption based on that is you are calling a compose function without a root to be able to attach itself.

if you comment out the SetContent function in your activity you can achieve the same result:

//setContent {
        epicContent()
//}

It sounds like you're calling a composable function outside of a composable function - it's like suspend, they can only be called from other composables

[Luca Nicoletti]

Trying to debug it, I have a breakpoint inside every @Composable function I have, it crashed before even reaching any breakpoints :s

[Ryan Mentley]

what's the stack trace?

[Luca Nicoletti]

Found out what was the problem 🙂

[Luca Nicoletti]

Was using some composable functions (+state) to assign values to val, outside of a @composable function

[Luca Nicoletti]

Not only in function though

[Luca Nicoletti]

You could declare them as I did in a class

@kioba That is the plan. We plan make effects @Composable functions that return values. When that is done they will be reported as errors just as trying to call an @Composable outside and @Composable is an error.
