Hi,
id of your TextFields should match name of property in Address model.
something like that..
public class Address {
private String address1;
private String address2;
private String city;
//getters
public String getAddress1(){}
...
}

Hi,
After searching unsuccessfully through the ML archive, I come here to seek
some advice on FormComponentPanels (FCP).
What I want to do is build a small, reusable form component that lets me
edit an Address (address, zipCode, city, country).
I know that FCP are usually used as a bridge between an external model and
a set of individual components ; but in my case, the internal and external
models are the same.
Below is my current code (adapted from Wicket In Action) ; as you can see,
it is very verbose and redundant.
public class AddressField extends FormComponentPanel<Address> {
private Address address = new Address();
private TextField<String> address1;
private TextField<String> address2;
private TextField<String> zipCode;
private TextField<String> city;
private CountryCodeDropDownChoice countryCode;
public AddressField(String id) {
super(id);
}
public AddressField(String id, IModel<Address> model) {
super(id, model);
}
// Constructor block
{
add(address1 = new TextField<String>("address1", new
PropertyModel<String>(address,"address1")));
add(address2 = new TextField<String>("address2", new
PropertyModel<String>(address, "address2")));
add(zipCode = new TextField<String>("zipCode", new
PropertyModel<String>(address, "zipCode")));
add(city = new TextField<String>("city", new
PropertyModel<String>(address, "city")));
add((countryCode = new CountryCodeDropDownChoice("countryCode", new
PropertyModel<String>(address, "countryCode"))).setRequired(true));
}
@Override
protected void onBeforeRender() {
Address modelAddress = getModelObject();
if (modelAddress != null) {
address.setAddress1(modelAddress.getAddress1());
address.setAddress2(modelAddress.getAddress2());
address.setZipCode(modelAddress.getZipCode());
address.setCity(modelAddress.getCity());
address.setCountryCode(modelAddress.getCountryCode());
}
if (address.getCountryCode() == null) {
address.setCountryCode(CountryUtils.CODE_FRANCE);
}
super.onBeforeRender();
}
@Override
protected void convertInput() {
address.setAddress1(address1.getConvertedInput());
address.setAddress2(address2.getConvertedInput());
address.setZipCode(zipCode.getConvertedInput());
address.setCity(city.getConvertedInput());
address.setCountryCode(countryCode.getConvertedInput());
setConvertedInput(address);
}
}
What I would like to achieve is something like this, using a
CompoundPropertyModel :
public class AddressField extends FormComponentPanel<Address> {
public AddressField(String id) {
this(id, null);
}
public AddressField(String id, IModel<Address> model) {
super(id, new *CompoundPropertyModel*<Address>(model));
}
// Constructor block
{
add(new TextField<String>("address1"));
add(new TextField<String>("address2"));
add(new TextField<String>("zipCode"));
add(new TextField<String>("city"));
add(new
CountryCodeDropDownChoice("countryCode").setRequired(true));
}
}
But I cannot figure out how to make it work properly (sometimes Wicket tells
me that it cannot find a getter, sometimes that it cannot bind to a null
model...). I must have missed something obvious ?
Thank you for you help !
Olivier
