Hello! I'm having some issues when trying to add custom headers to a

HttpServletResponse

within a suspend function. The approach we are using now is not good, so we would like to find a proper solution:

@GetMapping("/users")
suspend fun getUsers(//...parameters, response: HttpServletResponse): List<UsersResource> {
    val users = userService.searchBy(//parameters)
    response.addPaginationHeaders(users.size)
    return users
}

For instance,

addPaginationHeaders

will be changed only for example purposes, as below:

internal fun HttpServletResponse.addPaginationHeaders(size: Int) {
    val uri = ServletUriComponentBuilder.fromCurrentRequest().toUriString()
    setHeaders("X-Count", size)
    //...other params
}

So, suspend function doesn't work (throws

java.lang.IllegalStateException: No current ServletRequestAttributes

). Instead, we have to place the function body within a

runBlocking

to make it work.

suspend fun getUsers(\\...parameters, response: HttpServletResponse) = runBlocking {
    //same code as above
}

Has anyone experienced this issue? Is there any solution besides

runBlocking

?

Is there a way to navigate back inside a bottom sheet? I have 2 composables inside a bottom sheet. When I navigate to the second screen, the back button dismisses the bottom sheet instead of navigating back to the first screen. Navigation works well as long as the back button is not involved. Yet

BackHandler

inside the composables don’t get called 🤔

Hi, is there a way to serialize an enum as the ordinal without adding SerialName for each key ?

Hello, the code in the thread gives a warning. Is this intended behaviour or am I abusing Mockk?

When building an annotated string with

buildAnnotatedString

for a VisualTransformation for a TextField, I wanted some section of the text to be whatever the color already was, only with a lower alpha value. Best I found out how to do now was

// in composable context:
val mediumAlphaContentColor = LocalContentColor.current.copy(ContentAlpha.medium)
// Inside the visualTransformation not in a composable context
...
  buildAnnotatedString {
    append("")
    withStyle(SpanStyle(mediumAlphaContentColor))) {
      append("gray text")
    }
  }
}

But is there any API I can use to simply alter the alpha without changing the content color? Maybe in some span I am not gonna be using the LocalContentColor value and simply want to use whatever was there already. Maybe this isn’t possible though right?

I'm trying to setup my Kotlin project to run in WSL, but I just get this error and have no clue on how to fix it.

Is there a right way to use Jetpack Compose Navigation components with Koin?
