JavaFX: Specifying explicit type causes Illegal Forward Reference

Question

I can't seem to find a way to work around this, but if I specify some code like:
var txtField = SwingTextField {
    columns: 3
    text: "60"
    editable: true
    action: function() {
        someMethod();
var sceneMain:Scene = Scene { content: [
    txtField
var stage:Stage = Stage {
    title: "My App"
    width: 300
    height: 300
    scene: sceneMain
}I get an error on the declaration of txtField, saying I seed to specify an explicit type. OK, no problem, change the code to:
var txtField:SwingTextField = SwingTextField {However, now the compiler reports a warning on the line:
var sceneMain:Scene = Scene { content: [
    txtField
]}saying that there is an illegal forward reference to "txtField" here.
The really odd part is that this "illegal forward ref" only happens if txtField is defined with an explicit type. If I remove the need for an explicit type declaration by removing the action, the "illegal forward ref" warning goes away:
var txtField = SwingTextField {
    columns: 3
    text: "60"
    editable: true
    // action: function() {
    //    someMethod();
var sceneMain:Scene = Scene { content: [
    txtField
var stage:Stage = Stage {
    title: "My App"
    width: 300
    height: 300
    scene: sceneMain
}I can't seem to find a way around this one... is this a JFX bug? Thanks for any help!

Fixed code markup

Answer 1

Well, I guess I figured out my "error", though I'd argue its a problem with the way JavaFX loads its classes.
I can add 1 line to reference the button earlier and force it to load. Its a completely useless line, but for whatever reason gives the compiler enough of a hint to fix the error:
package testapp;
import javafx.stage.*;
import javafx.scene.*;
import javafx.ext.swing.*;
function setBpmFromTxt():Void {
    // validate some user input.
    // if a problem, show error scene:
    cmdStartStop;  // <-- Adding this fixes error. Does nothing at runtime, but tips off the compiler. Awesome!
    stage.scene = sceneError;
var cmdStartStop:SwingButton = SwingButton {
    action: function() {
            setBpmFromTxt();
var sceneError:Scene = Scene { content: [
var sceneMain:Scene = Scene { content: [
    cmdStartStop
var stage:Stage = Stage {
    scene: sceneMain
}
