Building an application in JavaFX, using a table to populate customer name and id and then added a button that launches another form once a customer name is selected from the table. I am getting errors in.
I have tried to change the name populateCustomerAllName, tried to change the return type
@FXML
public void handleAddButton() {
if(customerAllTable.getSelectionModel().getSelectedItem() != null) {
selectedCustomer = customerAllTable.getSelectionModel().getSelectedItem();
} else {
return;
}
Dialog<ButtonType> dialog = new Dialog();
dialog.initOwner(appointmentMain.getScene().getWindow());
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("AppointmentAdd.fxml"));
try {
dialog.getDialogPane().setContent(fxmlLoader.load());
} catch(IOException e) {
System.out.println("AppointmentAdd Error: " + e.getMessage());
}
ButtonType save = new ButtonType("Save", ButtonBar.ButtonData.OK_DONE);
dialog.getDialogPane().getButtonTypes().add(save);
dialog.getDialogPane().getButtonTypes().add(ButtonType.CANCEL);
AppointmentAddController controller = fxmlLoader.getController();
//error with populating .getCustomerAllName controller.populateCustomerAllName(selectedCustomer.getCustomerAllName());
dialog.showAndWait().ifPresent((response -> {
if(response == save) {
if(controller.handleAddAppointment(selectedCustomer.getCustomerAllId())) {
monthAptTable.setItems(AppointmentDB.getMonthlyAppointments(selectedCustomer.getCustomerAllId()));
weekAptTable.setItems(AppointmentDB.getWeeklyAppoinments(selectedCustomer.getCustomerAllId()));
} else {
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("Error");
alert.setHeaderText("Add Appointment Error");
alert.setContentText(controller.displayErrors());
alert.showAndWait().ifPresent((response2 -> {
if(response2 == ButtonType.OK) {
handleAddButton();
}
}));
}
}
}));
public void populateCustomerAllName(String name) {
customerAllName.setText(name);
}
Caused by: java.lang.NullPointerException
at views.AppointmentAddController.populateCustomerAllName(AppointmentAddController.java:170)
at views.AppointmentMainController.handleAddButton(AppointmentMainController.java:155)
Expected results are when clicking on the addAppointment button the customers name is populated into the customer field.
