Thanks for quick reply, Nino.
No, I'm not using ajax so far.
Let me describe a bit more: there's a registration page, which has a
RegisterForm. Also, the page has an OptionsPanel unrelated to the
RegisterForm with a language selector DDC. That DDC is bound to Session's
"language" property via PropertyModel. What I want is to reorder items in
RegisterForm's DDCs.
I've actually implemented it this way (list of countries is one of the lists
that must be reordered):
OptionsPanel:
add(new DDC(...) {
onSelectionChanged() {
...
((BasePage) getPage()).notifyLanguageSwitch();
}
});
RegisterPage:
RegisterPage extends BasePage {
init() {
...
processLocaleSpecificComponents();
...
}
notifyLanguageSwitch() {
processLocaleSpecificComponents();
}
processLocaleSpecificComponents() {
Component countriesChoice = get("countryChoice");
DDC newCountriesChoice = new DDC("countryChoice",
getCountriesList(getLanguageId()), new ChoiceRenderer(...));
if (countriesChoice != null) {
countriesChoice.replaceWith(newCountriesChoice);
} else {
add(countriesChoice);
}
}
}
But you're saying, I don't have to reconstruct components. How can I control
order of items in the DDC then? Even though data is provided dynamically,
like this:
add(new DropDownChoice("countryChoice", getCountriesList(getLanguageId()),
new ChoiceRenderer("name", "id"));
the getCountriesList() method isn't called when page is reloaded to switch
language.
