Davide,
you have to attach a model to the drop downlist that will hold the state
of each list.
you could to this:
create a MyDate class with integer fields for day, month, hour and
minute and the respective getters and setters.
then change your method so it takes a PropertyModel:
private FormComponent getIntegerDropDownChoice(String name, PropertyModel
model, int start,
int stop) {
DropDownChoice select = new DropDownChoice(name, model, getIntegerList(start,
stop));
return addRequiredValidator(select);
}
and add the dropdownchoices like so:
MyDate myDate = new MyDate(); (well, of course you have to remember the MyDate
instance across page calls and not build a new one each time...)
section1.add(getIntegerDropDownChoice("dateContainer.day", new PropertyModel(myDate,
"day"), 1, 31));
section1.add(getIntegerDropDownChoice("dateContainer.month", new PropertyModel(myDate,
"month"), 1, 12));
section1.add(getIntegerDropDownChoice("dateContainer.hour", new PropertyModel(myDate,
"hour"), 0, 23));
section1.add(getIntegerDropDownChoice("dateContainer.minute", new PropertyModel(myDate,
"minute"), 0, 59));
That should do the trick!

I have created a Form with several DropDownChoice... some of them
update the model but after the submit they lose their state (the first

and only one of them seems to work! :)
public Step1Form(String name, MyModel model) {
super(name, new CompoundPropertyModel(model));
Border section1 = new MyBorder("section1Border", "Title");
section1.add(getIntegerDropDownChoice("dateContainer.day", 1, 31));
section1.add(getIntegerDropDownChoice("dateContainer.month", 1, 12));
section1.add(getIntegerDropDownChoice("dateContainer.hour", 0, 23));
section1.add(getIntegerDropDownChoice("dateContainer.minute", 0, 59));
section1.add(addRequiredValidator(new CityDropDownChoice("city")));
...
private FormComponent getIntegerDropDownChoice(String name, int start,
int stop) {
DropDownChoice select = new DropDownChoice(name, getIntegerList(start, stop));
return addRequiredValidator(select);
}
Textfields works, and a Panel in the same page is updated with the same model.
I can't figure out what I'm doing wrong with these DropDownChoice elements... :(
Cheers,
