Well ok, but I am getting other values in the same instance of BookingModel
in onSubmit(). Here's my code
private class BookingForm extends Form {
private BookingModel bookingModel = new BookingModel();
public BookingForm(String id, RoomModel selectedRoom) {
super(id);
// -- adding the Room list dropdown
ArrayList list = new ArrayList(getRoomList());
ChoiceRenderer renderer = new ChoiceRenderer("roomName","roomID");
DropDownChoice roomDropDown = new DropDownChoice("roomlist", new
PropertyModel(bookingModel,"room"), new Model(list), renderer);
if(null!=selectedRoom)
bookingModel.setRoom(selectedRoom);
add(roomDropDown);
add(new TextArea("purpose",new
PropertyModel(bookingModel,"purpose")));
}
public final void onSubmit() {
System.out.println("room "+bookingModel.getRoom()); //
getting 'null'
here
System.out.println("purpose
"+bookingModel.getPurpose()); // getting
value here
}
}
I get value for the 'purpose' textarea. Thanks for your patience and
replying Igor, but how else can I get the instance of BookingModel inside
onSubmit() ? I tried getModel() - its giving null there. Is there any other
way ?
