I'm trying to build a register/login system using JavaFX, and I'm having a "Register a new account" button within the login form. My intention is to redirect the user to the registration page if he clicks on that button. The registration page shouldn't open in a new window, but within the same window as the login form.
This is the structure of my login-view.fxml file:
<VBox id="root" fx:id="rootPane" alignment="CENTER" spacing="20.0" xmlns="http://javafx.com/javafx/16" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.example.yuber.controllers.LoginController">
<padding>
<Insets bottom="20.0" left="20.0" right="20.0" top="20.0" />
</padding>
<VBox id="paneSmall" alignment="BASELINE_CENTER">
<Label id="title">Yuber</Label>
<TextField id="input" fx:id="username">Username</TextField>
<PasswordField id="input" fx:id="password">Password</PasswordField>
<Button id="btn-default-small" onAction="#onLoginButtonClick" text="Login" />
<Hyperlink onAction="#onRegisterButtonClick">Register a new account</Hyperlink>
<Label id="error" fx:id="error" />
</VBox>
</VBox>
As you can see, the parent tag is a VBox. I've found several answers on this website, all of them containing an AnchorPane as a parent element, but I'm pretty sure using a VBox won't affect everything that much and would most likely have the same effect.
Inside my controller, I have this line:
@FXML
private VBox rootPane;
and also this is the #onRegisterButtonClick event:
@FXML
protected void onRegisterButtonClick(ActionEvent event) throws IOException {
VBox pane = FXMLLoader.load(getClass().getResource("register-view.fxml"));
rootPane.getChildren().setAll(pane);
}
The problem is, my app throws a NullPointerException:
Caused by: java.lang.NullPointerException: Location is required.
Yes. The register-view.fxml file is inside my resources folder. It looks like that:
Also tried replacing the loader to use getClass().getClassLoader().getResource(...), and also Main.class.getClass().getClassLoader().getResource(...), but nothing seemed to fix it. The same error.
