Thanks Igor, that's certainly pushed me along in the right direction my only
problem is that I can't seem to get the value from the selected dropdown,
there are two drop downs that will always be used but I only care about the
2nd value(the phonemodel), the first, phone make, is just a means of
getting there.
I'm calling convertInput but I think I'm missing in some of my wicket
knowledge because it isn't working, sooo at the risk of being laughed at by
the greater wicket community here is my code.
public class PhoneComponentPanel extends FormComponentPanel
{
protected final Log logger = LogFactory.getLog(getClass());
PhoneMaker phoneMake;
Phone phoneModel;
Phone selectedPhone;
DropDownChoice phoneMakeSelect = new DropDownChoice("phoneMake");
DropDownChoice phoneModelSelect = new DropDownChoice("phoneModel");
private List<PhoneMaker> makerList = getPhoneMakers();
final HashMap<String, List> makeLookup = new HashMap<String, List>();
public PhoneComponentPanel(String id)
{
super(id);
init();
}
public PhoneComponentPanel(String id, Model model)
{
super(id, model);
init();
}
private void init()
{
logger.debug("Initialising PhoneComponentPanel");
// Create a list of all Make and models
for(PhoneMaker maker : makerList)
{
makeLookup.put(maker.getId(),
getUtilityService().getPhones(maker));
}
// Init the Phone Makers Drop Down with a the list of makers
logger.debug("about to initi phone make");
phoneMakeSelect.clearInput();
phoneMakeSelect.setModel(new Model(phoneMake));
phoneMakeSelect.setRequired(true);
phoneMakeSelect.setChoices(makerList);
phoneMakeSelect.setChoiceRenderer(new
PhoneMakerChoiceRenderer(makerList));
phoneMakeSelect.add(new
AjaxFormComponentUpdatingBehavior("onchange")
{
protected void onUpdate(AjaxRequestTarget target)
{
target.addComponent(phoneModelSelect);
}
});
add(phoneMakeSelect);
// Configure the choices for the model selection, this is dependant
on what has
// been select on the make selection
IModel modelChoices = new AbstractReadOnlyModel()
{
public Object getObject()
{
List models;
if (phoneMakeSelect.getInput() == null ||
phoneMakeSelect.getInput().equals("") )
{
// If no maker has been selected then return an empty
list
logger.debug("Phone make hasn't been selected returning
empty model list");
models = Collections.EMPTY_LIST;
} else
{
// The phone make has been selected
logger.debug("Phone make has been selected:
"+phoneMakeSelect.getInput());
models=makeLookup.get(phoneMakeSelect.getInput());
}
return models;
}
};
phoneModelSelect.setModel(new Model(phoneModel));
phoneModelSelect.setChoices(modelChoices);
phoneModelSelect.setChoiceRenderer(new PhoneChoiceRenderer());
phoneModelSelect.setOutputMarkupId(true);
phoneModelSelect.setRequired(true);
// Configure the phone model drop down
add(phoneModelSelect);
}
@Override
protected void convertInput()
{
logger.debug("!!!!!!!!!!!! CONVERTING INPUT!!!!!!!!!!!!!!!!!!");
setConvertedInput(phoneModelSelect.getConvertedInput());
}
public PhoneMaker getPhoneMake()
{
return phoneMake;
}
public void setPhoneMake(PhoneMaker phoneMake)
{
this.phoneMake = phoneMake;
}
public Phone getPhoneModel()
{
return phoneModel;
}
public void setPhoneModel(Phone phoneModel)
{
this.phoneModel = phoneModel;
}
}
I'm setting this up in a parent form with the Panel being declared as such
phonePanel = new PhoneComponentPanel("subscriber.phone", new
Model(selectedPhone));
add(phonePanel);
As always any assistance/ridicule in the right direction would be great.
Cheers
Simon
