java - Wicket: Update Model on DropDownChoice Item Selection Event -

i need update model or object after select dropdownchoice item.

bellow code i'm working:

add(new listview[company]("listcompanies", listdata) {      override protected def onbeforerender() {       //       // ...       super.onbeforerender()     }      def populateitem(item: listitem[company]) = {       var company = item.getmodelobject()        //...        val listclients: java.util.list[client] = clientcontroler.listclients         item.add(new dropdownchoice("clientselection", listclients,new choicerenderer[client]("name"))) 

in listview properties of company object, after choose name property of dropdownchoice, model company updated client name selected.

how can achieve this?

thanks

i think can override onselectionchanged. need override wantonselectionchangednotifications return true make work. this.

    dropdownchoice<client> dropdownchoice = new dropdownchoice("clientselection", listclients) {         @override         protected boolean wantonselectionchangednotifications() {             return true;         }          @override         protected void onselectionchanged(object newselection) {             // here when selection changed         }     };
