Thanx for the tip. It work on some cases. I found a pattern. For instance, if
a component (be it a textfield or a DropDownChoice) has it self a Model, for
instance a PropertyModel, the instance variables of the class that is used
on the form model (CompoundPropertyModel) are not filled.
EXAMPLE
the form:
public class ImovelHabitacionalForm extends Form {
private final ImovelHabitacionalInput
imovelHabitacionalInput = new ImovelHabitacionalInput();
...........
public ImovelHabitacionalForm() {
super(ID);
setModel(new
CompoundPropertyModel(imovelHabitacionalInput));
buildForm();
}
/*The components creations */
private void buildForm() {
/*TRANSACTION TYPES*/
List transactionTypes =
TipoTransaccaoFacade.getTipoTransaccoes();
transactionType = new
DropDownChoice("transactionType", transactionTypes);
/*DISTRICTS*/
DistritosModel
distritosModel = new DistritosModel();
selectedDistrito = new
SelectedChoice(); /*class with a instance variable "selectedChoice" and
getter and setter*/
distritosDDC = new
DropDownChoice("distritos", new PropertyModel(selectedDistrito,
"selectedChoice"), distritosModel);
/*PRICE*/
priceTextField = new
TextField("price");
/*AREA*/
/*Class with a variable name
area and a getter and a setter*/
private TextFieldAreaModel
areaModel = new TextFieldAreaModel();
areaTextField = new
TextField("area", new PropertyModel(areaModel, "area"));
}
}
/*Part of the user input class used on the form model*/
private class ImovelHabitacionalInput implements IClusterable {
private String district= "";
private String transactionType= "";
private String price= "";
private String area = "";
/*GETTERS AND SETTERS*/
}
When the form is submited happens that the transactionType and the price
variables on the class ImovelHabitacionalInput are filled with the values
inserted by the user, but the district and the area dont. the diferences
between the textfields and the dropdownchoices is that the transactionType
and the price doesn't have a model itself.
Does any one knows why if a model is supllyed to a form model, the
respective instance variables are not filled, even more, those getters and
setters are not called (in debug mode i noticed that too).
Thanks a lot everyone
