Select component and sorting order
Hi all,
I have a Country class with two-letter ISO3166 country codes, together with
a select component in a form. The problem now is the sort order of these
countries, default is the order within the enum, but that doesn't work very
well within a multi-language site. I want the sort order alphabetically
descending by the label of the countries in the corresponding property file
for the current locale. What is the recommended way to achieve this?
------------------
Country.java:
------------------
public enum Country {
AE, /* UNITED ARAB EMIRATES */
AR, /* ARGENTINA */
AT, /* AUSTRIA */
}
------------------
Page.java:
------------------
@Property
private Country country;
------------------
Page.tml:
------------------
<t:select t:id="country" blankOption="always"/>
------------------
country.properties:
------------------
country.AE=United Arab Emirates
country.AR=Argentina
country.AT=Austria
------------------
country_de.properties:
------------------
country.AE=Vereinigte Arabische Emirate
country.AR=Argentinien
country.AT=Österreich

Thanks Thiago, it is working now.
Here is what I did:
------------------
Page.java:
------------------
@Property
private Country country;
@Property
@SuppressWarnings("unused")
private SelectModel countryModel;
private Country[] getSortedCountries() {
SortedMap<String, Country> map = new TreeMap<String, Country>();
for (Country c : Country.values()) {
map.put(messages.get("country."+c),c);
}
return map.values().toArray(new Country[map.values().size()]);
}
public void onPrepare() {
countryModel = new EnumSelectModel(Country.class, messages,
getSortedCountries());
}
------------------
Page.tml:
------------------
<t:select t:id="country" t:model="countryModel" blankOption="always"/>

Use the model parameter of Select and provide the options in any sort
order you want. The SelectModelFactory will probably be useful.
