Scene Builder: Failed to load FXML file - javafx

I am Loading a Fxml file in scene builder and it's showing me the below error. I had external date picker code and i have commented it all still it's showing the error. Any help would be appreciable.
Loading of xyz.fxml has failed. Make sure it is a valid fxml file.
error: java.lang.UnSupportedOperationException
FXML
<AnchorPane id="AnchorPane" fx:id="view" " xmlns:fx="javafx.com/fxml"; fx:controller="com.nubes.labour.controller.DataSyncController">
<children>
<TextField fx:id="hoursText" layoutX="451.0" layoutY="342.0" prefWidth="45.0" />
<!-- <DatePicker id="toDatePick" fx:id="toDate" layoutX="448.0" layoutY="297.0" prefHeight="26.0" prefWidth="140.0" /> -->
</children>
</AnchorPane>

There are multiple issues in your fxml. It has an unwanted ; and ". The xmlns is also incorrect. I am not sure if you have the imports or just missed them while editing. Try the following fxml:
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane id="AnchorPane" fx:id="view" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.nubes.labour.controller.DataSyncController">
<children>
<TextField fx:id="hoursText" layoutX="451.0" layoutY="342.0" prefWidth="45.0" />
<!-- <DatePicker id="toDatePick" fx:id="toDate" layoutX="448.0" layoutY="297.0" prefHeight="26.0" prefWidth="140.0" /> -->
</children>
</AnchorPane>

I also visited this post and used fontawesomfx 8.4.but it didn't work.It shows the same exception.
Currently I am using java 18(jdk-18.0.2) and javafx-sdk-18.0.2 and SceneBuilder-18.0.0 and fontawesomefx 8.9 jar.I use visual studio code.I am not using any built tools for my project.
NOTE:If I run the code without any fontawesomefx icons, my code works fine.
I have been searching the solution for this problem for an entire day.Please explain me what is the problem and how to solve it.I want to use fontawesomeicons in my project.How to do it?
Thank you
You need to upgrade the version of fontawesomefx you are using to be compatible with your java version.
See the answer to this question, I believe your problem is the same as this person was seeing.

Using Unicode characters with JavaFX

I've been playing around with swing for some time and decided to check out FX now. So far I'm finding it a lot easier and more fun to work with as compared to swing but I've run into a small speed bump and after hours of looking around I just can't find a solution.
I am unable to use \u when I try to add it through the fxml file It works fine if I don't use the fxml but I want to use the scene builder as it is more convenient.
Here's the small piece of code:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.131" fx:controller="baitform.designDocController">
<children>
<Button fx:id="button" layoutX="126" layoutY="90" onAction="#handleButtonAction" text="Click Me!" />
<Label layoutX="145.0" layoutY="129.0" text="\u0644\u0627\u062B\u0627\u0646\u0649" />
</children>
</AnchorPane>
The error I keep getting is
Caused by: javafx.fxml.LoadException: Invalid escape sequence.
Not sure if relevant, but I'm using jdk1.8.0_131 & netbeans 8.2
If anyone could point me in the right direction here I'd really appreciate it.
FXML is an XML, and so you need to use XML escaping:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.131" fx:controller="baitform.designDocController">
<children>
<Button fx:id="button" layoutX="126" layoutY="90" onAction="#handleButtonAction" text="Click Me!" />
<Label layoutX="145.0" layoutY="129.0" text="لاثانى" />
</children>
</AnchorPane>
That being said, if you are able to input the characters, you can just insert them as is.

fx:script shows NullPointerException in scene builder

I am new with JavaFX FXML and I was trying fx:script with this "NMAESTAGE.fxml" file below:

</children>
</HBox>
</children>
<padding>
<Insets bottom="30.0" left="30.0" right="30.0" top="50.0" />
</padding>
</VBox>
But the problem is, when I try to open the fxml file in scene builder, the fx:script tag is causing a NullPointerException. It says that "make sure NAMESTAGE.fxml is a valid fxml file".
The application compiles, builds, and runs without any error.
Removing the 5 lines with fx:script tag along with the onAction="nextAction()" part, somehow solve the problem. I don't understand what I am doing wrong here. Could anybody help?
For me it's a bug, introduced by Scene Builder 2.0; the older versione (1.1) doesn't have the problem

To add actions in the controller for the buttons:
Add the controller class in SceneBuilder
To specify the controller's class check the right side of the SceneBuilder under the tab "Controller" is a text field named "Controller class". Also notice there is a list with all the node that have an "fx-id".
Add fx:id to all the nodes you need in controller
For any component that you need to work with in the controller add an fx:id. For actions check add a method name in the tab "Code" of any component. For example if you want an action for the button "Submit" add the name of the method there in the field "On Action" named "submitPushed"
In the controller's class add all the Nodes with fx:id
For every node you attributed with an fx:id you need to add it as a property in the controller class with the annotation #FXML. For a TextField with the fx:id textSubmit you will ad a property in the controller
#FXML TextField textSubmit
In the controller class define the methods for the actions
For the button named "Submit" with the action "submitPushed" you need to declare the method of the action
#FXML submitPushed(ActionEvent event){
//add code here for what the button should do
}
If you want to add the TextField's content to the TextArea when the button Submit is pushed
#FXML submitPushed(ActionEvent event){
String content=textField.getText();
String contentTextArea = textArea.getText();
textArea.setText(contentTextArea+"\n"+content);
}

JavaFX ScrollPane scrollbar is disabled

I have built a layout in SceneBuilder which has a ScrollPane (inside of a StackPane) containing a StackPane containing a Group (aligned to center-left) containing an ImageView. For some reason, whether I preview within SceneBuilder with Ctrl+P or run in my program, the horizontal scrollbar is disabled. The scrollbar does show that there is more to the right to be scrolled to, but I cannot scroll to it. It looks like this:
And here is the FXML:
<?xml version="1.0" encoding="UTF-8"?>

</ScrollPane>
<HBox id="toolbar" alignment="TOP_CENTER" prefHeight="100.0" prefWidth="200.0" spacing="8.0">

</BorderPane>
I've tried a horizontal scroll policy of both AS_NEEDED and ALWAYS.
You have numerous problems (most important is that the HBox with your controls covers your ScrollPane, intercepting that would otherwise go the ScrollPane):
Set preserveRatio="false" instead of preserveRatio="true" for your ImageView, otherwise the image may not grow to the fitWidth you provide (because it may hit the fitHeight limit first and not grow the width anymore).
Set maxHeight="-Infinity" on your HBox, (this will ensure that the maximum height of the HBox does not grow above the preferred height for the HBox, otherwise the HBox will intercept the mouse clicks intended for your ScrollPane). Either this, or set pickOnBounds="false" for the HBox, so that the HBox does not intercept mouse clicks for the ScrollPane even though it overlays the ScrollPane.
Note: to debug layout sizes, sometimes it is useful to temporarily add a background or border to a region to see it's true size, for example style="-fx-background-color: red;".
Also rather than placing your controls and image in a StackPane, which overlays content, maybe you might want to use a VBox instead, which instead lays things out vertically rather than on top of each other.
