Leland Richardson [G] · Answer

hmm this is likely from a situation where you are calling a composable function from outside of a composable function

Leland Richardson [G] · Answer

if you can narrow it down to the source code that triggers the error i d be interested in seeing it so we can have it fail earlier its supposed to be an IDE time error

Zsolt · Answer

I didn t add new code just updated dev05 gt dev07 I ll try to narrow it down

Leland Richardson [G] · Answer

yeah there was a very big infrastructural change to the compiler in dev06

Leland Richardson [G] · Answer

this wouldn t have failed prior to that

Zsolt · Answer

looks like I found it

Zsolt · Answer

so I had extension method ```private fun StackScope foo ``` with composables inside but no Composable annotation on it and calling it like `Stack foo `

Zsolt · Answer

funny thing is as soon as I commented out the call site IDE gave me warning correctly

Zsolt · Answer

but while it s being referenced it doesn t complain

Leland Richardson [G] · Answer

hmm can you paste more complete repro which part are you commenting out

Zsolt · Answer

sure

Zsolt · Answer

I was migrating Pokedex this file

Zsolt · Answer

Zsolt · Answer

you can see lines 53 59

Zsolt · Answer

if I comment them out IDE fails correctly that those extension methods don t have Composable annotation

Zsolt · Answer

but it doesn t fail if they re not commented out

Leland Richardson [G] · Answer

oh strange

Leland Richardson [G] · Answer

if you comment out the callsites in Content then the declarations like line 81 would show an error

Zsolt · Answer

yes all of them

Leland Richardson [G] · Answer

eek

Leland Richardson [G] · Answer

that s not good lol

Leland Richardson [G] · Answer

can you try removing `private` from all of them and see if that for some strange reason fixes it

Zsolt · Answer

sure

Leland Richardson [G] · Answer

sounds stupid but private access is implemented in strange ways in kotlin

Zsolt · Answer

nope even without private it gets to compiler exception

Leland Richardson [G] · Answer

the exception i would still expect to happen

Leland Richardson [G] · Answer

but i m wondering if the IDE is quicker to yell at you

Zsolt · Answer

I meant yes IDE lets it through without warning

Leland Richardson [G] · Answer

boo

Leland Richardson [G] · Answer

ok

Zsolt · Answer

private doesn t make a difference

Leland Richardson [G] · Answer

thanks

Zsolt · Answer

nw

Zsolt · Answer

thanks for useful pointer to problem

Leland Richardson [G] · Answer

i ll add this to the list of problems with our frontend analysis

Zsolt · Answer

but again point is IDE somehow still finds it if the call site is commented out not sure what difference it makes but might be a helpful detail

Leland Richardson [G] · Answer

yep that does help
