Java SE (Java Platform, Standard Edition)

Hello all

I'm having issues with trying to track down an error that I'm experiencing. Currently I'm working to include fxml data within a parent fxml file (as outlined in this thread), and I keep running into the error mentioned above. Now within this fxml file that I'm attempting to include, Here's the code for the fxml file in question

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>

<?import javafx.geometry.*?>

<?import javafx.scene.control.*?>

<?import javafx.scene.image.*?>

<?import javafx.scene.layout.*?>

<?import javafx.scene.layout.AnchorPane?>

<?import javafx.scene.layout.HBox?>

<?import javafx.scene.layout.VBox?>

<?import javafx.scene.text.*?>

<AnchorPane fx:id="textAreaAnchorPane" padding="$x1" prefHeight="177.0" prefWidth="918.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="com.package.childScreenController">

  <VBox alignment="CENTER" layoutX="15.0" layoutY="16.0" prefHeight="147.0" prefWidth="889.0">

    <children>

      <Text text="Choose your play type" textAlignment="CENTER" textOrigin="CENTER">

        <font>

          <Font size="28.0" />

        </font>

      </Text>

      <HBox alignment="TOP_CENTER" prefHeight="100.0" prefWidth="200.0">

        <children>

          <Button fx:id="firstButton" mnemonicParsing="false" onAction="#handleFirstButton" text="1 - First Button">

            <font>

              <Font size="16.0" fx:id="x2" />

            </font>

            <HBox.margin>

              <Insets bottom="15.0" left="15.0" right="15.0" top="15.0" fx:id="x1" />

            </HBox.margin>

          </Button>

          <Button fx:id="secondButton" font="$x2" mnemonicParsing="false" onAction="#handleSecondButton" text="2 - Second Button" HBox.margin="$x1" />

          <Button fx:id="thirdButton" font="$x2" mnemonicParsing="false" onAction="#handleThirdButton" text="3 - Third Button" HBox.margin="$x1" />

          <Button fx:id="fourthButton" font="$x2" mnemonicParsing="false" onAction="#handleFourthButton" text="4 - Fourth Button" HBox.margin="$x1" />

        </children>

      </HBox>

    </children>

  </VBox>

</AnchorPane>

What's throwing me is that I have no textField element, nor anything that would have a reference "field", at least that I'm seeing. Hence confused as to the source of this error, and how to resolve. Anyone happen to know more about this possible issue?
