JavaFX custom node creation - javafx

Question

I tried creating my own custom node, but I miserably failed somehow.
It always throws me an error when I try to run the controller/scene.
This is my class representing the custom node
package com.lollookup.scene.customcontrol;
import com.lollookup.scene.data.ChampionInfoData;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.Pane;
import javax.xml.soap.Text;
import java.io.IOException;
/**
* #author Yasin
*/
public class ChampionInfo extends Pane {
#FXML
private ImageView championImage;
#FXML
private Text KDA;
#FXML
private Text winRate;
#FXML
private Text masteryScore;
#FXML
private Text masteryLevel;
public ChampionInfo() {
try {
Parent root = FXMLLoader.load(getClass().getResource("championinfo.fxml"));
} catch (IOException e) {
e.printStackTrace();
}
}
public void setData(ChampionInfoData championInfoData) {
this.championImage.setImage(new Image(championInfoData.getUrl()));
this.KDA.setTextContent(championInfoData.getKDA());
this.winRate.setTextContent(championInfoData.getWinRate());
this.masteryScore.setTextContent(championInfoData.getMasteryScore());
this.masteryLevel.setTextContent(championInfoData.getMasteryLevel());
}
}
And this is my fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Separator?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.Text?>
<fx:root maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="84.0" prefWidth="238.0" type="Pane" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.lollookup.scene.customcontrol.ChampionInfo">
<children>
<Separator layoutY="3.0" prefHeight="0.0" prefWidth="238.0" />
<HBox prefHeight="84.0" prefWidth="200.0">
<children>
<ImageView fx:id="championImage" fitHeight="72.0" fitWidth="66.0" pickOnBounds="true" preserveRatio="true">
<HBox.margin>
<Insets left="10.0" top="10.0" />
</HBox.margin>
</ImageView>
<VBox prefHeight="200.0" prefWidth="100.0">
<children>
<Text fx:id="KDA" strokeType="OUTSIDE" strokeWidth="0.0" text="kda">
<VBox.margin>
<Insets top="10.0" />
</VBox.margin>
</Text>
<Text fx:id="winRate" strokeType="OUTSIDE" strokeWidth="0.0" text="winRate" />
<Text fx:id="masteryLevel" strokeType="OUTSIDE" strokeWidth="0.0" text="champLevel" />
<Text fx:id="masteryScore" strokeType="OUTSIDE" strokeWidth="0.0" text="champScore" />
</children>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</VBox>
</children>
</HBox>
<Separator layoutY="79.0" prefHeight="0.0" prefWidth="238.0" />
</children>
</fx:root>
My problem now is that somehow I can't really start/implement the custom node.
So no matter if I create a Scene like this:
package com.lollookup.scene.customcontrol;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.stage.Stage;
/**
* #author Yasin
*/
public class ChampionInfoExample extends Application {
#Override
public void start(Stage stage) throws Exception {
//ChampionInfo championInfo = new ChampionInfo(new ChampionInfoData("https://placeholdit.imgix.net/~text?txtsize=33&txt=350%C3%97150&w=350&h=150", "1:1", "50%", "0", "1"));
ChampionInfo championInfo = new ChampionInfo();
//championInfo.setData(new ChampionInfoData("https://placeholdit.imgix.net/~text?txtsize=33&txt=350%C3%97150&w=350&h=150", "1:1", "50%", "0", "1"));
stage.setScene(new Scene(championInfo));
stage.setTitle("Custom Control");
stage.setWidth(300);
stage.setHeight(200);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
or instantiate it like that:
Stream.of(championData).forEach(p -> championDataContainer.getChildren().add(new ChampionInfo()));
This is what is being thrown:

What should I do?
I'd appreciate any kind of assistance
Thanks
Edit:
After debugging, I kinda found out why it was null. Had nothing to do with the codes given. Thank you StackOverflow!
