selectonemenu controlls another

[garfield335]

Hello everybody.

I have 2 Databasetables, one with a list of countries another with a list of cities.

The user have first to choice the country and then select the city.

I used two h:selectOneMenu components,  the values of the second depends on the first component.

What is the best way to do this: ?

I have a Bean class which looks like this:

public class CityBean{

         private Long cityId;;
         private Long countryId;

         public SelectItem[] getCities(){ ... }
         public SelectItem[] getCountries() { ... }

        //getter and setters for cityId and countryId;
     
}

<h:selectOneMenu id="countrySelect" value="#{cityBean.countryId}">
                             <f:selectItems value="#{cityBean.countries}"
                                 id="si3" />
                         </h:selectOneMenu>
                         
                         <h:selectOneMenu id="citySelect" value="#{cityBean.cityId}>
                             <f:selectItems value="#{cityBean.cities}"
                                 id="si4" />
                         </h:selectOneMenu>
