Radio and Radio Group problems
Dear All
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.

Thank you for your reply, but with the form the problem is not solved (I
attach the code with the form).

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

Re: Radio and Radio Group problems
Posted by Michael O'Cleirigh <mi...@rivulet.ca>.
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();

Mike

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..
