I've been trying to get openIntenalWindow to work, but it keeps throwing an exception:

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method tornadofx.UIComponent.openInternalWindow, parameter owner

I've tried the simplest form of code I could think of and it still doesn't work:

class Start : App(MainView::class, HeaderStyle::class)

class MainView : View() {
    override val root = borderpane {
        openInternalWindow<FooView>()
    }
}


class FooView : View() {
    override val root = borderpane {

    }
}

fun main() = launch<Start>()

The tornadofx documentation feels really lackluster around this method. The example passes in an type Editor but I don't find anywhere it explains what that editor is

It appears I got it to work when initializing on button press, but not on instantiation of a view

[Hullaballoonatic]

is there anyway to get it to do that

I'm doing some cheeky shit to get it to open late

The View won't have an owner yet inside its constructor. Could you implement onDock in MainView and move the openInternalWindow call there?

Ah, onDock. That's what I was looking for. Thank you
