Always the last of the list is the selected.
I had tried also this proposal .. and it does not work.

Hello,
I don't think you need to track the selected (true/false) state your
self. Let the radio group model do it automatically for you like:
listLanguages.add(new NameWrapper("English", "en", "");
listLanguages.add(new NameWrapper("German", "de", ""));
listLanguages.add(new NameWrapper("French", "fr", ""));
listLanguages.add(new NameWrapper("Italian", "it", "");
listLanguages.add(new NameWrapper("Polish", "pl", "");
// set the selected radio to be the first in the list 'English'
final RadioGroup groupQuery = new RadioGroup("groupLanguagesQuery",
new Model<NameWrapper>(listLanguages.get(0)));
listLanguagesQuery = new ListView("listLanguagesQuery",listLanguages) {
protected void populateItem(ListItem item) {
String lang =
((NameWrapper)item.getModelObject()).getName();
item.add(new Label("nameLanguageQuery", new
StringResourceModel(lang, this, null,"XXXX")));
item.add(new Radio("checkLanguageQuery",
item.getModel(),groupQuery));
}
};
groupQuery.add(listLanguagesQuery);
Now the model object value of the RadioGroup 'groupQuery' will have
the NameWrapper for the selected choice. A NameWrapper instance is
selected if it is returned by groupQuery.getModelObject();
Regards,
Mike
I had tried this option and it does not work.

Hi,
.. i am not sure. The model of RadioGroup should contain, wich item is
selected. The model of Radio should reflect the associated value.
So if
model of RadioGroup contains "fr" and Property "selected" of item
nr. 3
is "fr" this Radio is selected.
maybe this will help..
mm:)
I have a problem when using the Radio component.
Using a list of languages, where each item is a NameWrapper object
with a property "selected". The property "selected" is associated
to the radio component.
However, when presenting to the user the corresponding list of
radios, the language Polish is true, and not English (it should be
the selected option).
listLanguages.add(new NameWrapper("English", "en", "", true));
listLanguages.add(new NameWrapper("German", "de", "", false));
listLanguages.add(new NameWrapper("French", "fr", "", false));
listLanguages.add(new NameWrapper("Italian", "it", "", false));
listLanguages.add(new NameWrapper("Polish", "pl", "", false));
final RadioGroup groupQuery = new
RadioGroup("groupLanguagesQuery", new Model());
listLanguagesQuery = new
ListView("listLanguagesQuery",listLanguages) {
protected void populateItem(ListItem item) {
String lang =
((NameWrapper)item.getModelObject()).getName();
item.add(new Label("nameLanguageQuery", new
StringResourceModel(lang, this, null,"XXXX")));
item.add(new Radio("checkLanguageQuery", new
PropertyModel(item.getModel(), "selected"),groupQuery));
}
};
groupQuery.add(listLanguagesQuery);
Any ideas? I really need to solve this issue.
Thank you so much.
