I’m having a weird error that I don’t understand. I have a kotlin “type-safe builder” for some html and in it I have 2 child elements, one of which is inside a when

div {
  h1 { ... }
  when (x) {
    A -> +"text"
    B -> div { ... }
  }
}

The actual model that this produces reverses the order of the h1 and the other child. The order is correct if I have the same but without the with construct. The same issue happens with if . Am I misunderstanding something about execution order in lambdas or something?

Is this kotlinx.html? The only reason that I could see causing this is an error in the implementation of the DSL, but that really shouldn't happen.

I'm using Kotlin React and that definitely doesn't happen (I use lambdas & when all the time)

indeed, the issue was unrelated and I just hadn’t been systematic enough in chasing down the issue 😞 The when had caused some unforeseen logical differences which should have been obvious to me
