I have an error at Line 7 :
@FXML
public void loginAction(ActionEvent actionEvent) {
try {
if (loginModel.loginAdmin(username.getText(), password.getText())) {
try {
StackPane home = FXMLLoader.load(getClass().getResource("../Views/Dashboard.fxml"));
stageController.stackPane.getChildren().setAll(home);
} catch (IOException e) {
e.printStackTrace();
}
} else {
loginHint.setText("Invalid username or password");
}
} catch (SQLException e) {
loginHint.setText("Login Failed");
e.printStackTrace();
}
}
The error is indicating that i have an NullPointerException, and how can i fix this?
