Update Model on DropDown Item Selection

[Bruno Moura]

I need to update a model or object immediately after select
a DropDownChoice item.


Bellow is the code that 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 the Listview with properties of Company Object,
after choose a name property of the DropDownChoice, the model
Company would be updated with the Client Name selected.

How can I achieve this?

Thanks
